I'm having this SAME issue. I had to get a jump after letting my battery drain (my fault there). The process was followed perfectly. Because I knew i'd have a recovering battery, I turned the infotainment system off by holding the power button for 3 seconds. My battery needed to be replaced after I noticed the truck struggling to start. I replaced the battery and it starts great, but my infotainment system hasn't come back on. It has been over 3 weeks! I tried the fuse and the blue cable behind the glove box, no results. The backup camera comes on when I reverse, but the backup guidance doesn't work (those are the orange and red lines that change as you move the steering wheel). The radio works via the steering wheel for about 15 min and then dies. I do not have an onstar account nor do I have a xm subscription, but I have seen a couple comments where calling onstar fixed the issue. I guess they can send a signal to the radio??? HELP IF YOU HAVE ANY ADVICE ON WHAT TO DO NEXT!!!
