Confused about Bose Lux vs. Non Lux

[alanca3]

Hey guys. I have a 2007 Yukon XL SLT. I currently have the "base" Premium Bose option without navigation. I want to upgrade the system, but keep everything stock.

From my understanding, I need the Bose Lux amp and a matching Bose Lux head unit because of the data bus.

I've found the OEM Bose Lux amplifier online, but I can't find the proper head unit part number anywhere. Does anyone know the part number for the navigation display unit for Bose Lux? Should I just call my dealer? There are lots of articles on this subject for the GMT-800 platform, but almost none for the GMT-900.

Since you have bose, you can just swap in the nav and have the dealer unlock it. Stock gm Nav requires an amp, bose systems have an amp under the center console. The luxery nav is 5.1 capable, whereas the premium one is not. You most likely have the premium bose system, although it was an option on slt's that have rear seat entertainment. Easiest way to tell is an extra speaker in the center of the dash for a total of 10. Or look in your glove box for code y91 or y92
