I gotta say that I am with you on this one. My Chevy Trailblazer has always-on 12V outlets, and I wish it was switched with the ignition. I don't need my radar detector or portable GPS on when I shut off the truck, so I have to power them down when I leave the car. I have an XM RoadyXT and I have mine set to shut off in an hour too. This is annoying, though when you are in the car more than an hour, and it turns itself off while you are driving...
