i've been using parallels for over two months to interface with my garmin gpsmap 60c using the usb connection. i've been able to do this without any problems until about two weeks ago. what changed, i don't know, i haven't changed or uploaded any new software. regardless, i now have difficulty interfacing with my gps, most of the time it will still work, but when i load maps onto the unit, the data is often corrupted and the autorouting features usually don't work. i've reloaded all software (parallels, windows, mapsource) and spent a lot of time on the phone trying to figure out the problem with garmin, even to the point that i got a brand new gps, but the problem persists. has anyone else had these issues, any suggestions what i can do about it? i'd like to stay on the mac, but thus far, it looks like i may have to get my money back for parallels and go back to a pc.
