I jus bought an used very low miles 12 Nissan Maxima, and it has the Bose radio and sounds decent. It has no bluetooth to the radio and I have read that the navigation model does have the bluetooth. I know you can buy the navigation, bezel, radio pretty much everything you need. My question is I'd like to keep that factory look not crazy putting a double din in but will the wire harness match up to the other screen and radio and AC controls? Is there hidden wires they jus didn't used on the wire harness back behind the dash, I know that happens sometime. Can anyone help?

 

I remember reading here that's the 2 systems are different and just a matter of plug and play, I might be wrong though.
