: 2011 Realtime Navigation?

11-14-10, 04:00 PM

I understand that the new nav units no longer operate from a disc, but from OnStar. Does this mean that we finally get realtime traffic and construction zone alerts? Does this also mean that if we do not carry-on with an OnStar subscription that we lose our navigation function when the 1-year free sub runs out?

I have a 2007 but I know the new ones use SD card instead of DVD. I assume you need a new download to the card when they make updates.
