Finally got it downloaded and flashed.

The Wayfinder MAP application took my navicore number and authenticated correctly.

Luckily I had already downloaded the USA West maps awhile back during the beta. I never could get the EAST maps downloaded. (And I have to go to the east coast for business soon... gonna need those maps or I'll be LOST.)

Anyway wayfinder maps works now... so I can keep OS2008 loaded this time.
