Today I woke up and the entire "infotainment" system on my 2017 Camaro is completely dead.
No navigation, no music, no Bluetooth phone, no backup camera, etc.
From advice I found on here, I tried pulling and putting back Circuit Breaker #2, I replaced the Display fuse in the trunk, and I tried the good old "disconnect the battery for an hour" trick. No luck.
It's important to note that I do hear radio static for about 15 minutes when I first start my car, and I can control its volume with the steering wheel controls, but then it disappears. Also, the backup camera works the first time I put the car in reverse after starting it, but then it disappears as well.
It appears that there might be a few TSBs relating to this, but I don't really understand those.
Any help or ideas would be GREATLY appreciated!
I really can't afford yet another $1k+ repair on this thing.
