After Market Navigation Options
I am considering a GXP and really want an integrated navigation system. I've checked around and been told that an integration kit is currently unavailable for the 2009 G8 and there is no confirmed plan to offer one.
What have 2009 G8 owners done for nav? Would I be stuck with a Garman mounted to my windshield? Also, does anyone have experience with On-Star's turn-by-turn, traffic updates? Is this service just as good?
