Alright guys i been trying to figure this out. How hard is it to replace my stock radio in my 2002 ml320 with bose but no navigation. Every site i search gives me like 3 different wiring harnesses to use. Does anyone have experience doing this succesfully and can tell me how to do it and how hard it is. I have done radios in the past on many cars but never had this hard of a time finding the correct harness that fits it and keep the amp. Please help me thank you guys.
