GM (General Motors) OEM GPS Touch Screen Navigation DVD/CD/XM/AM/FM Radio unit that will fit 2007-2013 GMC and Chevrolet Vehicles.  The GM Part# is 20883054 which has been replaced with GM Part# 22776895 and is same unit. Pictures are of the actual unit that you will be receiving.  This unit was removed from vehicle working perfectly. Only reason for replacement was an aftermarket upgrade.

This GPS unit is capable of playing DVD, CD, AM/FM Radio, SIRIUS/XM Satellite Radio has an Aux jack on the front for IPOD/MP3 players, and has capability to work with Hands-free Bluetooth. This will also work with RSE (Rear Seat Entertainment) and operate a rear backup camera.  This navigation unit is capable of hands free operation via voice recognition.

If you are looking for one of these for your vehicle, you know how expensive they are, even from the wholesalers

MSRP - $ 2084

Wholesale - $ 1442 - GMPartsGiant  (google it)

This fits many vehicles. It is your full responsibility to ensure that this is a fit for your vehicle.  I have seen several references to it fitting 2010, 2011 Avalanche, Silverado, Suburban, Tahoe, Sierra, Yukon, etc.  It may fit other years as well.  Verify your model, etc.  By the picture you can see the model # 20883054 which fits many vehicle models.  It has since been replaced with model 22776895 for the same vehicles to my understanding.  

This is ready to install.  The process is after it is installed (unless having a GM type dealer install it for you) is to have a GM type dealer (GMC, Chevy, Cadillac, etc.) match this unit to your car with their unlock procedure.  It takes about 20 minutes and they will charge you  0.5 (1/2 hour) worth of labor.  (Verified through 2 local dealers).  GM would have to do that with ANY replacement receivers despite what is sometimes claimed on the Internet.

Do your home work to ensure that this will work for you as their are no returns!
