You have to figure out what amp you have and can be determined by looking for the code in your glove box. OR look at the part number on the amp.


03 and 04 used a different non-touch screen nav
05 to 07 used the same touch screen with updated versions AND updated discs
08 and 09 is a complete revamp and I believe uses a diferent amp and has a different touch screen as well.

In all honesty, if you cannot find a factory nav for $400 or $500 UNLOCKED and programmed for your truck, I would look at the Pioneer Avic's. you can get them pretty cheap and will have the option of using your NAV and listening to CD's at the same time where 03 to 07 factory NAV's you cannot.
