Most Mercedes-Benz E-Class W211 comes with fiber optic amplifier in the trunk, please note the new Android head unit does not support fiber optic amp, so you need to use a long cable B5 connect speakers directly in the trunk. You can check the plug behind the factory radio so that you can know if there are fiber optic cables there, the above picture shows the fiber optic cables so this car has fiber optic amplifier.
If your car does not have fiber optic amp, you just need to use one of the short power cables as below:
There’s a wiring diagram at the bottom of the unit, so you can see how to connect all plugs behind.
Note: another long radio antenna cable is also included, for the car with fiber optic amplifier, you should use the long radio antenna cable.
The next step is to run the long cable to the trunk for w211 with fiber optic amp, a professional mechanic can do it for you easily. You can run the long wires under the carpet along the door frames, removed the back seat to get access to the trunk, and hid the wires behind the cover panel in the trunk.
