Hello,

I am installing a D3 today in my 2001 Mercedes ML320. The forum on Benzworld.org suggests using a Metra Volkswagon harness to adapt the Pioneer wiring to the mercedes. I have one OEM lead which is the amp wake up and cannot see what lead on the D3 will work with this. All other leads have been accounted for.

The remote turn on

blue/white wire off the avic

No it's not, it's the blue/white wire on the rca harness. There aren't any wires that come off the avic.
