Anyone out there with a Garmin SP2610 or other portable NAV system that uses Mapsource City Navigator? I'm asking b/c I got an e-mail to upgrade my current version 6.3 to their new version 7.

Anyone else do this? It costs $150 to upgrade, which I think is a ripoff, but if its worth it, I'll do it. Unless someone has a copy they want to share.
