Touchscreen blank after jumpstart
Chevy equinox 2015 v6
this afternoon the vehicle wouldn't start, could hear clicking like the battery was dead, battery seemed strong when started in the morning. My wife got a jump start and drove it home, the touchscreen was blank and no turn signal sounds after starting. When i got home the i checked the voltage at the battery 12.7v vehicle started fine & the battery was charging at 15.1 volts.
Battery terminals look perfect.
It is the original battery and never had any issues with it.
Everything else seems fine, is there a fuse to check, or someway to reset screen? Help

If the battery was improperly jumped, you may have blown the "Mega Fuse" in the fuse box under the hood. Any other electrical features not working? My wife had her 07 Equinox jump started improperly and she lost her power steering.

Ultimately, when I determined there was a 3.7amp draw that had and was draining the battery I decided to pull fuses to determine what was causing the draw.
Turns out the RDO radio/touchscreen was the culprit as the drain stopped as soon as I pulled that fuse. When I plugged it back in it reset the radio/touchscreen and it everything started working normally. I still didn't trust that the problem was permanently fixed. I pulled the fuse at night and left in when i drove it. I took it into the Chevy dealer 3 days later they couldn't find anything wrong except for a weak battery, no firmware update was done.
So they overcharged me for a new battery and diagnostics and hopefully the seemingly random draw the drained the battery will not repeat itself.
