Radio Mounting Kit

This kit is designed to hold a standard double din radio.  It holds the radio in place and also fills the open space left after removing your radio.  It is painted to match the finish of your dashboard.

Radio Wiring Harness

Main Radio wiring harness (if your new radio has 4 or 5 volt RCA amplifier outputs)

This harness connects to the factory wiring behind the radio as long as your radio has 4 or 5 volt RCA outputs


Main Radio wiring harness with HILO BOX (if your new radio has 2 volt RCA amplifier outputs)

This harness is the same as above but if you radio has low 2 Volt RCA outputs then you need this harness to make the audio sound as good as radios with 4V or 5V RCA outputs.


Main Radio wiring harness for aftermarket amplifiers

If you are completely removing the factory Mercedes Audio system you can use this box to give you the functions above but not keep the factory audio Amplifier.

Steering wheel Control Programmer

The SRWH-W211 above has the electronics to do steering wheel controls but this wire will tell it what radio you are installing.  Since it is radio specific it is sold separately.  If we do not have one for your brand radio use the universal one.

Plug and Play Converter

The harness above has an ISO connector on the radio side.  This will plug into some radios.  Check the google sheet on this products page to see if your radio will connect directly of of you will need to buy a converter to do a plug and play free installation. 

AM/FM Antenna adapter

This is a windshield mount antenna.  This is what we recommend when replacing the radio in this car.

Backup Camera

We are currently looking for a new supplier for our camera.  We have no estimated date

Backup camera power adapter.

Out main harness has a reverse wire to tell your radio that you are in reverse.  This wire does not have enough power to power a camera.  If you connect a camera you will blow up the little box and void your warranty. This harness grabs power from the main wire and used our weak signal as a switch.

  • Enfig SRWH-BUC


    Gives power to a backup camera when using our SRWH main harness

Panel Pry Tools

These tools come in handy when removing the cars interior trim.



For this car we recommend the Sony XAV-AX5500 Sony XAV-AX5600,Sony XAV-AX4000 and Sony XAV-AX6000 because the 5V RCA outputs make the factory audio system sound as good or better than stock.


If you are bypassing the CD Changer you will need the factory Mercedes pocket to fill the hole.  We do not sell it but here is a link to where you can buy it on Amazon
