I am in need of assistance with a command for my 04 ML. The dealer says that they are discontinued. My was sent for repair and it came back smashed into pieces. The number of my original is 163-820-03-79. I tried several from eBay but nobody seems to have any that work (even though they say they will work from 02 - 05). I also called Crutchfield and they claim I would have to change everything to make an aftermarket one work (speakers & amp).
Any help is appreciated.
