Alright to save you time, I stupidly left something on and drained my new AGM H7 battery dead on the 2012 Cruze Eco. Now that everything is charged back up, the radio and radio displays are completely dead. Nothing. I will note that when I took the passenger seat out and ran an errand, the radio and system was flickering in and out so I put the seat back in ASAP right before the battery flatline incident. Any thoughts? Is the control unit fried? I've checked fuses and tried to force a power cycle by unplugging from battery once charged too. Nothin. Thanks for any help!
