This post will teach you how to remove the factory w211 radio and install the new Android w211 head unit.

Firstly you should prepare a plastic installation pry tool, if you don’t have you can use a flat screw driver instead.

In order to remove the factory radio you can try the following steps:

After the factory Mercedes W211 radio removed, you can start to install the new Android head unit.

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.

How to connect plugs in the trunk?

Firstly you need to find out the exact location of your fiber optic amplifier in the trunk.

The fiber optic amp is located behind a metal bracket as below, so you need to remove a screw in order to see the amp:

CANBUS decoder should connect to the power cable with a small white plug, the CAN-BUS decoder is used to support steering wheel controls.

Important note if there’s no power on the unit after installation

If there’s no power on the radio after installation, please check the CAN plug, you may plug the wrong CAN plug in the trunk, the right plug goes in with a click and a solid connection. The wrong plug is loose and wants to fall out.

Regularly the right CAN plug is shown as above at right, 99.9% possibilities. If the unit still can not turn on, you can try the other CAN plug. And check if your car’s fuse was burned, you can measure the voltage from the yellow wire and see if it’s 12V.
