Product Information
D8-W211 & N7-MBE PRO Radio MOST Adapter
The D8-W211 & N7-MBE PRO Radio MOST Adapter is designed for fiber optic audio integration with the Dynavin. This product integrates with the factory amp but requires multiple interfaces with the Dynavin. The adapter comes with wire harnesses, CANbus wires, and a MOST box that allows for easy installation.
Product Usage Instructions
- Plug in the appropriate wire harness into the OEM radio plug.
- Plug the green and white CANbus wires into the CANbus distribution block under the glove compartment. The amp is turned on and off via CAN signals. The factory CAN wires are brown/red in a twisted pair.
- Unclog the two orange fiber optic wires from the factory plug and plug them into the MOST box.
- Plug the 14-pin plug from the MOST wire harness into the MOST box. Push in firmly until it clicks.
- The yellow and black wires are the power connections that match up to the factory radio plug. Plug them in as the main power plug.
- Plug the red and white RCA FRONT outputs from the head unit into the red and white inputs on the MOST box.

MOST Adapters Install for fiber optic audio integration
The Dynavin integrates with the factory amp but the system in those Mercedes is fairly complicated and has multiple interfaces with the Dynavin. If any of these are not done, you will not get sound.
- Plug in the appropriate wire harness into the OEM radio plug. The green and white CANbus wires must be plugged into the CANbus distribution block under the glove compartment. The amp is turned on and off via CAN signals. The factory CAN wires are brown/red in a twisted pair.
- The two orange fiber optic wires unclog from the factory plug and plug into the MOST box.
- The 14-pin plug from the MOST wire harness plugs into the MOST box. Push in firmly until it clicks.
- This is the main power plug. The yellow and black wires are the power connections that match up to the factory radio plug.
- The red and white RCA FRONT outputs from the head unit must be plugged into the red and white RCAs that are part of the MOST wire harness. These run to the MOST box so that the audio signal gets to the MOST box where it is converted to fiber optic.
- The DSP setting on the Dynavin in the “Audio” menu must be set correctly (the on/off setting will vary by car so you should try both).
- ALL the fiber optic MOST plugs must be plugged in. MOST is a loop, unplugging a device breaks the loop and it will not function. So, if you have a device like a CD player/changer it must be bypassed using a MOST bypass loop which are inexpensive (available on Amazon, eBay).
- A low battery can also cause issues with any of the above.

- If you are not getting audio after checking the above. There is a reset procedure for the factory “gateway” amp. (These cars are known for issues like this, even when stock.) Read about it here: http://www.mercedesmedic.com/no-sound/
