So, I have a 2005 Cayenne Turbo with the Nav and Bose option as stock, and I want to switch out the head unit for something with better nav, bluetooth and iPod connectivity. Key questions are:

1) What head unit? I'm leaning towards the Pioneer AVIC-Z120BT, but I'm open to ideas.
2) Will it work with the factory GPS receiver?
3) What about a backup camera? I don't have one, and it would be nice to have one when I have tint, and my subdivision doesn't believe in nighttime illumination. Is it a simple installation?
4) Speaking of installation, is it relatively straightforward, or are there any nasty gremlins befalling the unwary?

Answers will be repped to the best of my ability.

 

You will need the Cayenne MOST-HUR from NAV-TV. This is the Only way to swap out your Head unit and retain the factory wiring, amps etc -
