2007 G35x - radio navigation and climate control not working

[Tower07]

I have an 07 with Bose and nav when I turned my car on the Infiniti logo comes up on the screen but nothing else works on the screen, buttons and dial below, I can't operate the climate control though it seems to be stuck on the last temperature. The hazards and disc eject work. Anyone know what parts id need to fix this and is there a video / illustration on removal out there? THANKS

Those systems are probably the most complicated things in our cars. If you want to dive in, your service manuals are here:
http://www.nicoclub.com/FSM/G35/Sedan/2007_G35_Sedan/
"av.pdf" is Audio, Visual & Nav
"pg.pdf" is Power & Ground
"hac.pdf" is Heating & Air Conditioning Control System

I guess the first thing to do is check all related fuses - and there are probably several, in several locations... Beyond that you might need to bring it to somebody who has a Consult II and have it diagnosed. Could save you many hours.

Is it stock Bose/Nav? Is the backup camera working?

I assume this is a coupe? If so it's probably the circuit board. These guys have been known to repair them: http://www.shortcircuitrepair.com/

It's a sedan I brought it to the dealer and they said it was the main head unit. They wanted over $1000 to do the job. I bought the model number on eBay (looks like there is 3 models that can be used interchangeably) for $150. I'm going to put this in and give a write up when done.
