Just letting folks know that I succesfully installed a factory Navigation system with video input into my Z1 06 Tahoe. I got everything I needed on ebay. It was really easy and no cutting of any wires was required for the nav system. Plug and play.
There is a company called PAC that makes all the accessories to make watching TV on your factory navigation system a piece of cake. Here is the link to the VCI-GM2 that worked great for me.

I also installed rca connectors in my glove box for ipod video and sound input and ran jumper rca jacks up the roof liner to the dvd system to interface with that unit so video from the ipod works on both the nav system and the rear seat entertainment system.
This is a great setup and is fairly inexpensive. On top of that I got one of those $40 rear cameras from ebay and installed that as well. So I got the following
- Navigation Touch screen
- Rear camera
- Ipod sound input
If anyone wants to do this as well I can post part numbers.
