I have a 2003 infiniti M45, and it comes stock with a **** tape player... I have a new headunit I want to install but its not the usual wires in normal harnesses. I have tried to install it without an interface unit, since I cant find one anywhere. PAC audio, Scosche, Metra... nobody makes any kind of an integration module for this vehicle.. Do I need to bypass the Bose system? I am lost with this vehicle.. I have installed many of audio systems in day, but never worked with any kind of a databus set-up before and never had an issue getting power to my unit. I have included a diagram of the harnesses and the wires. A lot of these wires Ive never heard of and have no idea what to tie in with them.. If someone can please help me / walk me thru this I would really appreciate it. I am getting so tired of this **** tape player and still having to use a AUX jack tape adapter.. Please someone give me some insight! Thank you very much
