This user’s manual does not cover all possible installation scenarios.
If you feel you can’t install this unit yourself, take it to a local car audio professional. Feel free to contact us if you have questions about installing your radio.
• Do not disassemble or modify the unit or attempt to repair the unit yourself. If the unit needs to be repaired, consult your dealer or Retro Manufacturing, LLC.
• Do not use the unit when it is out of order. If the unit is out of order or is in an abnormal state (has foreign objects in it, is exposed to water, is smoking or smells), turn it off immediately and consult your dealer or Retro Manufacturing, LLC.
• Refer fuse replacement to qualified service personnel. When the fuse blows, eliminate the cause and have it replaced by a qualified service technician with the fuse prescribed for this unit. Incorrect replacement of the fuse may lead to smoke, fire and damage to the unit.
• If the unit does not turn on, check the connections first. Then check the fuse in your vehicle’s fuse box and the fuse at the unit’s wiring harness. Do not expose the unit to direct sunlight or excessive heat. Excessive heat will raise the interior temperature of the unit, which may damage it.
• Do not use the unit where it is exposed to moisture or dust. Exposure of the unit to moisture or dust may lead to smoke, fire or other damage to the unit and will void your warranty. Make sure the unit does not get wet in car washes or on rainy days.

• Refer wiring and installation to qualified service personnel. Installation of this unit requires special skills and experience. For maximum safety, have it installed by your dealer or qualified service professional. Retro Manufacturing, LLC is not liable for any problems resulting from improper installation of the unit. Please be sure to follow the instructions carefully while attempting installation.
• Follow instructions to wire the unit. Failure to follow the instructions could cause damage to the unit, fire, injury or death.
• Be careful not to damage the leads. Prevent them from being caught in the vehicle chassis or from being damaged by screws or moving parts such as seat rails. Do not scratch, pull, bend or twist the leads. Do not install them near heat sources or place heavy objects on them. If leads must be routed around sharp metal edges, protect them by wrapping them with vinyl tape or similar protections.

NOTE: Cutting the main wire harness, antenna lead, USB or auxiliary cables will void the warranty of your radio.

• Use the designated parts and appropriate tools to install this unit. The use of parts other than those supplied may result in internal damage to the unit.
• Do not interfere with safety-related vehicle components. Do not wire or affix this unit to the fuel tank, brakes, suspension, steering wheel, pedals, etc. Check for electric wiring, piping and other items before installing the unit.
• Never install the unit in a location where it interferes with your field of vision.

• Never splice into the power lead to supply other equipment with power.
• After installation and wiring, always check the normal operation of other electrical equipment.
• Make sure that no wires interfere with driving or getting in and out of the vehicle.
• Insulate all exposed wires to prevent short-circuiting or electric shock.
• Do not operate the unit for prolonged periods with the engine off. Prolonged operation with the engine turned off will drain the battery.
• To prevent accidents, keep the volume of your radio at a level that allows you to hear outside noises such as emergency sirens and train crossing warnings. Prolonged exposure to high volume levels may also result in hearing loss.
• This unit requires 12 volts to both the red and yellow power leads. The unit will not work without power to both of these leads.
• Disconnect the negative (-) battery cable before beginning installation. Verify the battery ground by checking that one wire is connected to the vehicle’s starter mounting bolt or engine block and the other to the vehicle’s chassis using at least 8 gauge wire. Make sure the alternator or generator connections are secure and free from corrosion, rust or dirt.
• This unit is designed for operation with a negative ground 12 volt DC battery system. Do not operate this unit with         other battery systems, especially an 18 or 24 volt DC or a positive ground system. If you have a 6 volt system, you need to either convert to 12 volt DC or purchase a separate inverter that would increase the voltage to 12 volts.

NOTE: The inverter needs to be rated at 10 amps or higher in order for the radio to operate properly.



STEP 1: Install the Radio Face

Plug the ribbon cable included with the Motor 6 body into the radio face. After plugging in the face, attach it to the body and tighten the four radio face mounting screws provided in the radio face box (the screws are very small and are in the hardware bag with the shaft nuts).
The RetroSound® logo on the Motor 6 body should be facing upwards. Take care to not install the face to the body upside down.
NOTE: Optionally, the radio face can be mounted remotely up to nine feet away from the Motor 6 body using an optional Face to Body Extension Cable. In some installation applications, a bracket can be used to mount the face to the body at an angle.

Figure 1 – Attach the Radio Face
Radio Face

STEP 2: Install InfiniMount Brackets

Attach each InfiniMount bracket to the correct side of the radio using the supplied screws. Before tightening the screws, you need to adjust the brackets up, down, forward or backward. You may also rotate, cut, or bend the brackets to achieve the perfect fit
(See Figure 2). Complete the assembly with at least two screws tightened on each side.

NOTE: In some installations, the brackets must be moved far enough forward or backwards or rotated so that only two screws will align with the threaded screw holes on the radio. Two screws are sufficient to hold the brackets in place.

NOTE: You may need to cut, trim or bend the brackets to achieve a perfect fit. You can even drill new mounting holes into the bracket if you need to. The InfiniMount system is designed to be modified. Modifying your brackets will NOT void your warranty.
Figure 2 – Attach InfiniMount Brackets

STEP 3: Mount InfiniMount Shafts to Brackets

To match the location of your shafts to the proper width of your vehicle’s dash, first, measure the distance between your existing shaft holes from centre to centre. Mount a shaft to each bracket using the supplied shaft nuts and washers. Finger tighten the shaft nuts to prepare for the final installation (See Figure 3). Once you ensure proper width, tighten the screws and nuts (DO NOT OVERTIGHTEN).


Finally, plug the shafts into each side of the main unit (See Figure 4).

Figure 3 – Mount Shafts to Brackets Shaft Washers Shaft Nuts
Figure 4 – Plug Shafts into the Body
Figure 5 – Wiring Diagram

NOTE: Cutting the wiring harness, antenna lead or auxiliary cable will void your warranty.
STEP 4: Complete Wiring Connections Connect Main Harness to back of Radio DAB+ Input

NOTE: This unit requires +12 volts to both the red and yellow wires to operate properly. Locate the three wire harnesses: main wire harness, power wire harness and speaker wire harness (See “What’s in the Box”). First connect the main wire harness to the back of the radio. Then connect both the power and speaker wire harnesses to the black female plug of the main wire harness.
After doing this, connect the bare wire ends of your power and speaker wires to the appropriate power and speaker locations in your vehicle (See Figure 5). Have your radio installed by a professional if this part of the install is too difficult, or contact us if you have questions.

Installation Notes
• To prevent damage to the unit, do not connect the power connector until you have completed the wiring process.
• This is a 12 volt negative ground ONLY radio. If you have a positive ground, or a 6 volt system, you need to either convert to 12 volts or purchase a separate inverter that would increase the voltage to 12 volts.
• Please note that any inverter must be rated at 10 amps or higher in order for the radio to operate properly.
Rear AUX Inputs
Two AUX inputs are located at the rear of the Motor 6 radio body. These auxiliary inputs allow you to listen to any external source with a standard headphone output. An example of an external source would be a MP3 player, iPod® or iPhone®, portable CD player or portable satellite radio receiver. To use this input, the auxiliary cable must be routed to an accessible area during installation.

Rear USB Inputs
Two USB connector cables are located at the rear of the Motor 6 radio body. During installation, you must route the cables to a convenient and accessible location for plugging in USB devices. If the cables provided are not long enough, you may use our optional USB/AUX Extension Cable (not included) to extend the reach of the cable. This cable also allows you to install the USB/AUX port into the factory location for the cigarette lighter for a factory look and easy access.

STEP 5: Finish the Installation

IF USING A BEZEL, Place the bezel on the face of the radio, then install the assembled radio from behind the dash until the bezel and radio face are flush with the front of the dash and the radio shafts protrude through the shaft openings in the dash. Using the supplied washers and shaft nuts (see “What’s In the Box” ), secure the radio to the dash.
IF USING A FACEPLATE, slide the radio into the hole from behind the dash, then align the faceplate over the radio shafts from the front. Using the supplied washers and shaft nuts (see “What’s In the Box” ), secure the faceplate to the dash and the radio.

Next, you’ll need to secure the rear of the radio using the supplied back strap and hardware (See “What’s in the Box” ). The back strap mounts using the threads in the rear of the radio body and can be bent and adjusted to align with the mounting point of the original factory radio behind the dash.

Figure 6 – Installing the Back strap

Finally, slide the rear knobs over the shafts, rotating them into the correct position, and push them into place. Mount the front knobs by gently pressing them onto the shaft.

Radio Data System (RDS) ON/OFF
This sub-menu allows you to turn on or off the RDS function. The default is RDS ON.
RDS tuners can automatically tune in stations according to the style of music (or talk) they broadcast. Some RDS tuners can even break in with traffic alerts or emergency broadcasts. RDS enables your receiver to display text messages (usually call letters and format info) that many FM stations include on a sub-carrier signal within their normal broadcast signal.
The RDS function is always active, and if the FM station you are listening to is broadcasting RDS information, the radio station call letters, song info, artist info and other messages will appear. Not all FM stations use RDS nor will all RDS functions work in the US.
Program Type (PTY)
This sub-menu only works in Europe (AREA EUR) and allows you select up to 31 pre-defined program types allowing you to find similar programming by genre. To change your program type, first make sure the tuner is set to AREA EUR. Then cycle through the sub-menu system until you see PTY. Now press the left front knob to activate, then turn the right front knob to
select from the program type list. Simply allow the menu to time out and your selection will be enabled. Now you will see PTY SEEK on the screen which indicates that the radio is searching the FM band for stations with your selected program type. If none are found, you will see NONE FOUND on the screen, and it will revert back to the last station selected.

Alternative Frequency (AF) ON/OFF
This sub-menu allows the radio to automatically search for another frequency that provides the same station when the signal gets weak. Traffic Announcements (TA) ON/OFF
This sub-menu allows you to turn the traffic announcements feature on or off. The traffic announcements function is part of RDS and allows FM stations to broadcast traffic announcements that scroll across the screen or audible traffic alerts to your radio. Simply rotate the knob to choose between TA ON or TA OFF and allow the display to time out to enable your choice.
Clock Time (CT) ON/OFF
This sub-menu allows you to turn the clock time feature on or off. If the radio station supports clock time, your radio will synchronize its clock with the radio station’s clock.

Motor 6 has the capability to receive radio broadcasts from around the world. This sub-menu allows you to adjust to broadcasts in your country. Factory default setting is United States (USA). Turn the right front knob (#8) to toggle between Europe (EUR), Australia (AUS), Japan (JAP) and Russia (RUS). To confirm the change, pause to let the sub-menu revert to your tuner. You will see your selected tuner mode: AREA USA, AREA EUR, AREA AUS, AREA JAP, AREA RUS.
Volume Last/Adjust
This sub-menu allows you to adjust the volume level that the radio first turns on to. The factory default setting is VOL LAST, which sets the turn on volume at the last volume used. VOL ADJUST allows you to preset the volume level that the radio turns on at from 0-46.


Connecting a USB Device
The USB 1 and USB 2 inputs are located at the rear of the radio body. The USB cables must be routed to a convenient and
accessible location for plugging in USB devices. Once you’ve turned on your radio and connected your flash drive, iPod®/iPhone® or supported USB device to the USB input, the radio will find your songs and automatically begin playing them.
The icon appears on the LCD during USB playback.
To change songs, rotate the right front knob (#8) to access the next or previous song. The preset buttons on the front of the radio’s control face (#3-7) will allow you to play/pause (#3), listen to 10 seconds of each song (INT) (#4), repeat the track you’re listening to (RPT) (#5) or randomly select from all songs on the attached flash drive or supported USB device (RDM) (#6). About MP3/WMA/FLAC Files
MP3 (MPEG Audio Layer-3), FLAC (Free Lossless Audio Codec) and WMA (Windows Media Audio) is a format for compressed audio files. When your radio is in USB mode (USB 1 or USB 2), you can play MP3 and unprotected (no DRM) WMA files off the flash drive.
Common facts about these compressed-sound formats:
• High bit rate and high sampling frequencies are recommended for high sound quality.
• Selecting VBR (Variable Bit Rate) is not recommended because playing time is not displayed properly and there may be some audible skipping artifacts. The playback sound quality differs depending on the encoding circumstances. For details, refer to the user manual of your encoding software.
• When adding MP3 files to your flash drive, it is recommended to set the bit rate to 128 kbps or more and “fixed.”
• When adding WMA files to your flash drive, it is recommended to set the bit rate to 64 kbps or more and “fixed.” Do not set the copy protect attribute on the WMA file or you will not be able to play the track.
• Motor 6 will read only FAT32 formatted flash drives. This radio will NOT read NTFS formatted drives.
• Motor 6 will read files placed in the root directory first before playing files in the folder structure of the drive. Please note that files are read in order of creation NOT alphabetically or numerically. Older files will get read first in a folder. Caution! Except for private use, duplicating audio data (including MP3/WMA) or distributing, transferring or copying it, whether free or paid for without permission of the original copyright holder is strictly prohibited by law and international treaty. Viewing MP3/WMA Song Information When playing MP3/WMA files from the USB source, you can view the track name, album, artist info (ID-3) information automatically from these files. Once the USB drive is inserted, the following info will scroll across the screen in the following order: F-DIR (folder directory), MP3 FILE (file name of song), ALBUM (name of album)      ARTIST (name of artist), SONG (name of song).
To access the clock when in USB mode, turn the left rear knob counter-clockwise. The clock will time out after a few seconds and will revert to the ID-3 information. Turning the left rear knob counterclockwise again will revert to viewing the ID-3 information on-screen.
The preset buttons (#3-7) on the front of the radio’s control face will allow you to play/pause, listen to 10 seconds of each song (INTro), randomly shuffle all songs (RDM) and navigate folders.
To play or pause, press button (#3).
To activate/deactivate scan, press button (#4).
To activate/deactivate shuffle, press button (#5).
To go to the previous folder, press button (#6).
To go to the next folder, press button (#7).
To switch to the next song, rotate the right front-knob (#8) clockwise.
To switch to the previous song, rotate the right-front knob (#8) counter-clockwise.
To activate/deactivate repeat, turn the right rear knob (#9) clockwise.


Bluetooth® Hands-Free and A2DP Streaming Operation You can make or receive phone calls using a Bluetooth® enabled
phone connected to your radio, controlling basic functions via the radio interface. During a call, the radio music source will be muted and the call broadcast through your car speaker system. You can also listen to music stored on a A2DP enabled Bluetooth® device.
Pairing a Bluetooth® Device
When connecting a Bluetooth® device for the first time, you must first pair the device with the unit. For most devices, pairing only needs to be done once.
1. To pair your device first make sure the Bluetooth® function is turned on in the radio sub-menu.
2. Then, change the BT DISCON function to BT CONNEC to make your radio discoverable (ensure Bluetooth® is enabled on your device).
3. Next, search for a new Bluetooth® device from the phone (this may take up to 30 seconds) and select “RETROSOUND” from the Bluetooth® device list.
4. If prompted, enter “0000” for the PIN. If successful, “PAIRING OK” will be displayed on the LCD screen. The paired device will then connect to your radio automatically. On some devices, you may need to select “SET AS AUTHORIZED” or similar to ensure your radio will automatically pair on future usage.
PAIRED NOTIFICATION DISPLAY: When the Bluetooth® device is paired with your radio, the Bluetooth® icon will appear on the LCD screen. This will occur whenever you use the system while the paired device is within range.

Placing a Call
1. Dial the desired number on the paired phone.
2. Once dialing is in progress, CALLING will appear on the screen.
3. Once the call is in progress, TALK will appear on the screen along with the elapsed call time (TALK 00:00).
Receiving a Call
1. If a call is incoming, any audio playback from the current source will either be muted or paused (depending on the source) and PHONE IN will be shown on the screen along with the caller ID if it is enabled by the phone/carrier.
2. To accept the call, turn the left-rear knob (#2) counter-clockwise.
Ending a Call
1. To end the call, turn the left rear-knob (#2) counter-clockwise.

To restore/reset the unit to factory defaults, remove all power from the unit, wait at least 2 minutes and then reconnect power. Resetting your unit will not remove your station presets but will reset the clock.


Do your radios work on 6 volt systems or on positive ground systems?
No. Our radios are 12 volt, negative ground only. After-market converters and inverters are available but must have at least 10
amps of continuous output.

I’m having problems getting the radio to turn on.
RetroSound® radios require 12 volts to both power leads. The red lead (+12 volt accessory) goes to a switched power source, and the yellow to a constant +12 volt power source. Using a volt meter, check the voltage when the key is turned from “off” to “on”. If there is a significant drop in the voltage, the circuit the yellow lead is attached to cannot handle the additional draw of the radio. You will need to find another circuit that can handle the additional draw of the radio, or you will need to go directly to the battery.

What speaker wire do you recommend I use?
We recommend using 16 gauge wire for the speakers..

I have all 4 speakers connected to your radio and the display is lit up like it is working, but there’s no sound coming out.
This usually indicates one of two things:
• Speaker wires touching each other or the vehicle chassis at some point. Check each speaker lead from radio to speaker.
• Speaker impedance below 4 ohms. Older speakers are usually not compatible with modern electronics.

My car originally came with a switch to control my automatic antenna. Can I use the RetroSound ® radio’s remote antenna
wire to control my antenna?
No you cannot. Your factory antenna is known as “semiautomatic.” It requires a switch to either extend or retract the antenna. You must retain this switch to control your antenna; the RetroSound® radio’s power antenna wire is for more modern “fullyautomatic” antennas not requiring a separate switch.

The sound output is all mid-range, with very little bass and a strangled-sounding upper range. What is wrong?
One of your speaker wires is connected backwards. This is called being “out of phase.” Check to make sure positive is wired to
positive and negative to negative on all your speakers.

Will cutting or bending the InfiniMount brackets void the warranty or harm the unit?
No. The RetroSound® patented InfiniMount bracket system has been designed specifically to be bent, cut and modified to simplify radio installation. Modification to the radio’s brackets is actually encouraged to ensure proper fit.
If you have questions about modifying the bracket system, feel free to contact us.

How much should I tighten the shaft nuts when installing the brackets and mounting the radio to the dash?
DO NOT OVERTIGHTEN the shaft nuts. The shaft nuts are NOT the only means of securing the radio to the dash. There is a back strap included which works with the shaft nuts to secure the radio to the dash. Please note that over-tightening the shaft nuts could break the shafts. Retro Manufacturing, LLC will not be responsible for broken shafts due to over-tightening of the shaft nuts.

I have your radio with an amp connected, but hear a whining/buzzing sound through the speakers when I step on the accelerator.
If you have an external amplifier installed and experience a highpitched noise that varies with the engine’s RPM, there are many possible solutions:
• Make sure the amplifier’s gain controls are not turned all the way up. Amplifiers amplify everything, including noise.
• Try grounding the amplifier near where it is installed.
• Try a filter on the amplifier’s 12 volt power lead. Make sure to use a filter that includes a ground wire.
• On rare occasions, noise can be introduced through the antenna lead. If disconnecting the antenna makes the noise go away, you need to replace or repair the antenna plug where it goes into the radio.

When I plug in my flash drive the screen says USB ERR, and it won’t play the files I placed on the drive.
• Make sure the files on the drive are .mp3, flac or unprotected .wma (Windows Media Audio) files. iTunes files are .m4a format and need to be converted to .mp3 format, which can easily be done using iTunes.
• Verify the capacity of the flash drive. Motor 6 will only play 1 gig up to 32 gig size flash drives.
• Make sure the flash drive is not NTFS formatted. Always use the FAT32 format (most drives are formatted with FAT32 from the factory). Be sure to do a full format rather than a quick format, and check that none of the files or folders have names longer than 64 characters. It is very important that none of the audio files have DRM. Use only MP3 files or unprotected Windows Media format files.
