Hi again, so I took a 2019 Chevy blazer down to Florida and wouldn’t you know it I needed maps to work and it failed working after the first day luckily my friend had an older iPhone 14 and it worked fine when I got back I remembered there’s a way to reset the GM infotainment system. It’s called a hard reset. Here’s the process if there’s a secret door that is a valet door that’s the thing that you’re gonna open and close if you have a valet equipped glove box that’s the thing you’re gonna open and close so you have to reverse it depending upon if you’re opening and closing it but the other parts of the procedure work.
This version is for the Cadillac so you have to reverse it because you’re using the glove box instead of that secret compartment so when it says open the face, but you’re opening the glove box and when you’re saying lower the face plate, you’re closing the glove box, ug!
Turn the vehicle on
Open the CUE faceplate, thereby exposing the storage area behind it
With the faceplate up, turn off the vehicle
Open the drivers side door
Wait 30-60 seconds with the drivers side door open
Close the door and start the vehicle
Lower the faceplate
Note: a hard reset or restart does not reset system settings or remove user-set items such as favorites.
