Went to add a new key fob to my wife's 2006 Equinox today. Connected up and got only to the 'initializing' boot screen. Tried it again on the Trailblazer with the same results. Also works the same with the supplied 12v adapter. I'm trying to imagine what it could be. Has power....could it have corrupted it's PCMIA card software? Without the card it boots to the same point. Has it bricked?
