The search feature is a great tool, just like me... (pause for effect)

But I have two questions... so far I havent been able to find a wiring harness for the car (pics would be helpful BEFORE I take the bezel off) And I am planning on getting the NAV bezel from MOPAR. Is there any other kit or bracket that I will need to securely install this in the dash? Or will it fit with the supplied factory NAV/RER bracket?

you should still need a dash kit. check metraonline.com for info. and youll need a typical crysler CAN_BUS adapter i use peripheral ones but i definetly cant recomend them, not saying they suck but i have had problems. youll also need an antenna adapter metra model number 40-cr10. good luck.

part number for the dash kit is 99-6510.

you can use the can-bus adapter or be a cheapa$$ and just catch acc. off the cig lighter...did it in my 06kota and havnt ever had any problems but the canbus adapter is the "correct way"

canbus also givees you a useable vss, illumination, and reverse leads right at the radio.

OK, so forgive me here, that's what this forum is for anyway... Does the car already have a CANBUS interface? How would I integrate the AVIC to the system?

The cars electronics communicate to each other through a system called canbus. An interface like the pac c2r-chy talk to the canbus system in the vehicle and translate info from that to something an aftermarket radio can understand.
