No stereo or heater control lights what could be wrong

[Equinoxlover]

Yesterday I filled up the tires in 2012 .The car has sat for 2 or 3 months. Car started up fine took it out for a drive. Noticed no stereo at all. Screen was blank. daughter drove car to work and said no backup camera no heater control lights and no turn signal noise. Is this a fuse and if so where and which fuse

I wonder if disconnecting the battery for 3-5 minutes, then connecting it again, if may re-boot the computer? It works with home computers sometimes. Just a thought..

Thanks, tried that. It's funny how much that controls. What I am reading is even if I replace the unit, I will still have issues. I am told I need to take it to a dealer and maybe needs reprogramed

Well it seems to have fixed itself. My daughter needed to the car and everything came back slowly

the whole issue could have been low battery voltage. As it was driven more and the battery charged up, things normalized. Just a guess, due to the fact these things get weird electrical gremlins when the battery is low.
