Car Solutions RGB-LE-V3.1
Price: USD 190.
Car video interface for Mercedes-Benz W220 allows connection and usage of external video devices such as DVD player, TV tuner, rear view camera, etc. on your built-in monitor.
- Composite video (CVBS) input (external video source) x 2
- Composite video (CVBS) input (rear camera source - automatically switchable) x 1
- Analog RGB input (car commander original monitor output) x 1
- Analog RGB input (aftermarket navigation system output) (option) x 1
- Composite video (CVBS) output (video out for headrest monitor installation) x 1
- RGB output (to W220 COMAND) x 1
- Audio select output x 1
Switch input mode:
- Possible to mute each input by operating DIP switches.
- Possible to switch input source with remote control or toggle switch.
- Rear view camera mode - rear view camera is switched on when the vehicle is reversing (not possible to switch to the rear mode with the toggle or the remote control).
Dimensions: horizontal - 129mm, vertical - 75mm, height - 21mm.
This port is used to connect power cable with fuse box.
RGB converter accepts input power: 8V~18V DC. Power consumption max 5 watt. Installed fuse has 5A 250V rating. Measured power consumption around 230mA (2.7W) of current, therefore, it should not be left connected directly to the battery. It is safe to connect the interface to ignition wire (e.g., cigarette lighter wire) since if not connected to power source, the COMAND will work in pass-through mode acting as if multimedia interface is not installed.

This port is used to connect video input source toggle switch.
AV source switching order: OEM - RGB - AV1 - AV2.
Note that rear camera av source is not switchable using input source switching. As a workaround the rear camera can be connected also to CVBS1 or CVBS2.
Note that RGB converter makes loud clicking noise when switching between sources.
This port is used to connect infrared receiver for the remote control. For the 4-pin connector only 3 pins are used.
Remote control is powered by CR2025 battery.
In practice only the "OK" button works, which switches between video sources (the same way as the toggle switch).
This port is used to connect the first video input (CVBS1).
This port is used to connect the second video input (CVBS1).
This port is used to connect the rear view camera video input.
This port outputs currently selected video input. Can be used to send currently displayed video to headrest monitor.
This port is used to connect navigation input (analog RGB).
This port is used to connect original video input (analog RGB).
This port connects to the RGB interface installed in W220 COMAND. The package comes with additional universal RGB connector (not needed for multimedia interface use with COMAND).
DIP switch allows to skip some inputs which are not connected.
|1||RGB INPUT SKIP||ON: Skipping RGB mode|
|2||CVBS1 MUTE||ON: Skipping CVBS1 input|
|3||CVBS2 MUTE||ON: Skipping CVBS2 input|
|4||CAN||ON: When installing to the Cayenne|
|5||OEM MUTE||ON: Skipping OEM input|
|7||REAR MODE||ON: External rear camera installed|
|8||SYNC ON GREEN||ON: Sync on green (RGSB)|
OEM MUTE will make multimedia interface always on and video from the COMAND itself will not be shown.
If the displayed screen vibrates, try to operate DIP switch number 6 (interlace mode) after turning power off.
This 3-PIN port gives voltage on one PIN at a time, depending on the video source that is currently selected - REAR-SEL (white), AV1-SEL (yellow), NAVI-SEL (gray). For example, 12V output is on yellow wire when AV1 input source is chosen. Can be used to activate appropriate audio output.
First LED lamp indicates that interface is on.
Second LED lamp indicates that AV sources connected work well.
RGB interface board for W220 COMAND has a simple task to hijack COMAND video output when video input is received from RGB converter.
Remove the COMAND from the vehicle using COMAND removal instructions.
If COMAND display works fine, but all video sources produce flickering image shown below, the ribbon cables are connected in the opposite order.
