Installing GMC Factory Nav?

[BigBake]

I have an 07 Yukon Denali that I bought without NAV after a few months I decided I need it. I called a GMC dealer so I could find out what the part # is for the head unit and they wouldnt give it to me :mad2: They told me they will not sell, nor install the factory NAV and therefore dont have the part #!:confused2: I see all these Nav units for sale on the internet with GM part #'s and they just told me they didnt exsist. Even after I read the guy the part numbers he told me it wasnt valid!

So what is the correct part # for the Navigation head unit for an 07 Yukon Denali with Bose system & xm?

What all do I need besides the head unit? The antena, backup camera, & nav CD? Whats there part numbers?

If GM is telling me they will not install it....who will? Doesnt a GM mechanic have to unlock it some how?

I'm really pissed off about this whole thing

There are a couple Nav systems depending on your vehicles setup. For example the part number of one I just sold 15940103, I believe the other part number is 15940102. Read this forum about installing the Nav. IT is actually really easy. Kind of plug and play. If the nav system was pulled from another car you will need to go to the dealer and have them unlock it. Other than that you will just need the Nav antenna and Nav disc. Read these forum posts on installing it and you will have everything you need to know about installing it.
