1. Good for you. Glad you got this irritant resolved (on your own). I am ocd and would have lost it over something like this. I feel your previous pain. 2. As far gm figuring stuff out....i am batting about .600 with dealerships figuring out legitimate warranty issues that are their issue / responsibility. Sad fact: get used to that. Ref your issue/scenario: been there, done that, got the t-shirt. Case in point : my nav head unit bought it some weeks ago. D-E-D dead. They replaced it. It was acting wonky as hell after they did though, so they told me. Kept it 3 days, no resolution. Insisted on taking it home. It was wonky, that was true, acting bizarre, but working to some degree. Disconnected battery overnight. All normal since. Don't ask me why. That worked. They didn't try that in the 3 days they had it. No judgement. Just observation. Is what it is anymore.
