I haven't5 been able to get this to work for Garmin streepilot c330. says I can't update the maps. Tried it two ways...
1. Through mapsource, with the map unlocked, it says it can't install.
2. Putting the file in the garmin folder on an SD card and putting the card in the GPS and turning it on...it doesn't pass the garmin load screen.

Any suggestions?

Thanks
