It needs to be programmed because the v.i.n. in it is from another vehicle.That might not even work. You may have to order by v.i.n a replacement from a place called technicar. Google it

After i cannibalized the screen, we had the dealer flash the vehicle. are the software updates vin specific ?
GMC Mechanic: Todd Audette, A.S.E Certified Master Technician replied 6 months ago

Yes. All depending on how they programmed it. You can chose program or replace and program. Replace and program will unlock the radio and everything should work unless you just have a bad radio
