Garmin StreetPilot 2660, 2650, 2620, 2610 Updates
Garmin today released software updates for the StreetPilot 2660, 2650, 2620, and StreetPilot 2610. The new version number is 4.60. The software includes mproved WAAS search and selection process to be smarter in its handling of multiple SBAS service providers, overlapping service volumes, and exceptional conditions. It also corrects a problem that could cause the Mileage Log distance to become corrupted, resulting in a distance that is displayed as all underscores.
