Would the hd navigation update the same way with a disk?

They're $200 from GM. Garmin updates are free, over the internet!! Get with it, GM!!

Not only are the Garmin updates FREE, but they're FREQUENT! And they won't hose other parts of your vehicle. As far as GM getting with it, now that's downright funny.

Buzz off dude. You're not wanted here. And you're an embarrassment to Texas.
