Garret Toomey just upgraded my Z3 HD and installed the latest maps. (he has previously unlocked the drive).

 

The best part -- 5 days total, Tuesday to Saturday, from Tennessee to Texas and back! Unreal turn-around time!

 

Haven't been anywhere to comment on the map quality, but one change jumps out. Driveways and private drives are now in a different color from streets.

 

If you have an Avic you gotta have Garret!
