2002 CLK 320
02 clk320 stereo wiring
So I am looking into installing an aftermarket stereo but I haven't the slightest clue where to start on this car. I've installed aftermarket radios in all of my cars that I've owned in the past so installing it won't be an issue.
I can't seem to find a wiring diagram not for the specific year. And other than losing steering wheel controls do I need the interface for it?
Also the car has what looks like a microphone beside the sos button. Does it work?

2002 CLK 430
theres a wiring diagram on the sticky on how to and a wiring diagram from southwest star on how to do it with a PAC system. but if you want to save yourself some trouble get the CRUX SWRBM-57C for 1999-2002 CLK w208 the wiring is already done and has controls for steering wheel. I found that you do not need the CRUX CS-LOC1 as it makes the audio line quieter and the max audio is half of its actual capacity mind you that i am using a SONY XAV-AX4000 that has built in pre amp and I am not getting any audio issues as a direct line in. My car is a CLK 430 2002 with a bose audio system. the amp on needs to be attached to the accessory power.
Here is a complete and CORRECT list of all wires in the Amplifier plug
