Navigation Upgrade

[2kwik4u]

I am looking to have a navigation system installed in my 2000 Escalade. Does anyone know of an in-dash system that works. I have seen alot on the GM part #15204335 which was made for 2003s, does anyone know if it works??

are you wanting to go with factory parts? cause if not, pioneer and kenwood both make nice flip out touch screen's with nav.
