Can this new system be installed in the 2003 Hummer as an upgrade?

I checked with the service manager last week about the possibilities of adding the '04 navigation in an '03. He told me it would be cheaper in the long run to trade my '03 in.

I was told by Delco that it is plug and play, So I checked with the dealer and they dont have a clue. There is a Totaled 04 ALREADY in the local yard that I looked at friday and the plugs on the back are the same. The screen was hit by somthing and looks like blue ink between two peices of plastic... Damn....

I have a '04 with Nav and wish I would of ordered with the standard radio and put an aftermarket Alpine or Pioneer Nav system in it. The factory nav has several limitations such as you can not play a cd while navigating since you have to have the nav disk in while navigating. With aftermarket you can do a lot more like add a cd changer, add XM, use the screen for DVD display, better and easier to use nav system, etc

If your interested in selling your NAV unit let me know at [email protected] It can be fitted into a 2003 and it has been done. GM does NOT recommend it though.
