i have a 2001 clk 55 and i need help with installing the avic d3.

If anyone has done this before please help me asap.

Also hopefully a wiring diagram would be greatly appreciated also.

I can help you, where you located?

vw wiring harness will work for this car. 2 wires are backwards though

^Usually constant and switched. Test before connecting the radio.

Yes VW plug will work, speaker wires are good, power plug is a little messed up, I got clk430, so don't know if yours are the same, you might have to test it, all you need is thick brown with pink for power, black for power, and blue to turn amp, also acc. wire is not on my power plug(really strange) I had to find other 4 wire unused plug that had ACC wire. I also have problems with my AVIC-D3 it sees no satillites, do you have a good signal? Also VSS wire under a sill on pass door, it's kind of hard to find.
