According to a Chevy dealer, you'll have to reset the infotainment Center system. All you have to do is press and hold the phone hang up button on the steering wheel for about 10 seconds or so. Screen will go dark and start with the resetting process. Then you just wait until everything comes back up.
I just purchased a 2022 Silverado 1500 LT. Does anyone know of a way to brighten the backup camera guidelines? There doesn't seem to be any backup camera settings. I tried the dimmer buttons, but it didn't help.I thought they might be more visible in a darker setting, so I pulled into my garage with the lights off. No change. Not a huge issue, but it would be nice to see the lines more distinctly.
