Talk to me about that OnStar module upgrade. My '06 has the "olde" OnStar, and turn-by-turn is a kludge. I understand that the '07 model has the "good" turn-by-turn; i.e., that it works in an integrated fashion w/ the nav' system. Does a module replacement solve this? If so, what's the cost of the upgrade?

I have the old analog system. My dealer told me they would change this to the digital system for $200 which is the cost for 1 year of On Star's cheap subscription.
