I bought an aftermarket large screen ("Tesla style") radio for my 2013 Maxima and everything except climate control works. Is there a diagram as to what are the different connectors on the back of the original radio?
I looked up the bottom module connected to the radio and found out that's the BOSE amplifier (?). I'm guessing blue one is USB in.

Thank you

 

You're in luck. See signature for factory service manual which contains the wiring diagrams.

 

Thank you. LAN doc is the one.
