I’m just wondering has anybody tried to identify each wire in both the S trim level and SV/SR trim level? I purchased a head unit out of a SR model. Everything plugs up except for the antenna which I think can be modded to fit. The plug is slightly different. The USB and the main two white plugs connect with out issue. The head unit powers up and works. The USB in the center console works. The overhead Bluetooth mics, back up cam and steering wheel controls do not. I’m trying to figure out is it simply that the plug/harness needs to be re-wired? Or does the head unit need to be updated? Does there need to be one of those canbus things to interpret? Or is it simply just not compatible?
