S320 head unit won't turn on missing amplifier issue
Greetings, first time posting and a new owner of a 2005 S320 CDI, i bought this car in descent shape but with knowing that few things are broken and i tend to fix them, my main problem know is that the command/ head unit won't turn on. so i see there is a missing amp (i think in the back of that car) i call the dealer ship and they tell me the part number for it is A220 870 17 89 and i was just wondering if somebody had replaced them before and what plugs should be in the car for it, if you look at the picture i took, i only have 2 plugs and a ground wire that has been cut. is that enough plugs or are there some missing? (there is another amplifier in the trunk already that is connected. And could the missing amp be my problem with the head unit not turning on?
Best regards, Kiddi the plugs that i was talking about
I assume that you have checked the fuse - did you use the correct fuse chart for your car to ensure that you were checking the correct fuse?
My 2003 COMAND unit had a fuse on the back of the unit - it wasn't on the fuse chart.
You need to know what the electronic box in the bottom of the fender is. There are several units that usually live back there - audio amp, telephone control, CD player, etc. Most certain way will be to get the part number off the existing unit and look it up. On my cars, the audio amp was the bottom box in the stack.

also all the components were connected in a fiber optic loop so you can’t just remove unneeded ones like the telephone or cd without using a fiber optic bypass wire to complete the loop to connect it all
