Mine will not work for DAYS sometimes, and the screen will flash on and right back off once every minute like it is “trying” to boot up. But this has gone on for so long now (over six months) that I know it will not pick up and work until after the GMC logo page appears. I thought it might be a bad contact in the module because it would come on first thing in the morning if it was ‘cold’ outside and then not connect in the afternoon. I am at a loss for a reason. But if this is how GMC manages these issues by just ignoring them. I will trade this 2019 GMC Sierra 1500 with the Elevation package in on a Dodge.
