I bought a macbook and installed parallels with windowsXP. I'm trying to run the Garmin mapsource software. Everything seems to works fine until I plug in the GPS unit. Parallels acknowledges the plugging in the Garmin GPS. But the subsequent message is this: No other app is open except the Garmin software. I've tried it with Garmin program closed and get the same message. I tried updating the Parallels program, no joy! Not sure what to try next? Bootcamp?, Vmware?, Do I uninstall the Parallels? I'm feeling pretty stupid for buying this macbook now. Seems like I should have just bought an IBM thinkpad or some cheap laptop to run the Garmin "Mapsource". I put the Macbook in a drawer and am back on my trusty old G4 powerbook.
