2019 GMC Sierra 1500 Crew Cab Denali 4dr Crew Cab 4WD 5.8 ft. SB (5.3L 8cyl 8A)
Purchased one of the first redesigned Sierras that the dealer had on the lot. Low level Denali trim with the pro tailgate. The upgraded stereo system with Nav IS VERY GLITCHY. System gets confused between Bluetooth and Android auto. Bluetooth is slow to respond and does not keep up the song title on the display when streaming. On a trip up to the mountains of N Arizona, the system (phone, radio, Nav) stopped working completely. No way to reset it. Next day it was fine. Using the USB outlet next to the Nav SD card slot confuses the system by saying SD card was removed.....not the case. Will take it in to have system evaluated. Btw heard similar problems with a 2017 Sierra HD pickup. GM can do better.
