Hi
I have just purchased a download map City Navigator Europe NT and have attempted to download it from MyGarmin to an SD card on my Zumo 660 several times. Each time it takes anywhere from 7 to 25 minutes and shows as completed. It even asks me to provide an email to be notified of future updates. However the file size for the gmappsup.img file varies between 294mb and 594mb each time. Even though the download is supposed to be 3.5gb?!
When I return to myGarmin myMaps the map shows with my zumo device but the Download Now option is still available. Whereas my City Navigator North America NT on the same device shows with a Get Garmin Express button next to it (Which I already have).
I am downloading using ie 11 with the garmin communicator add on enabled and pop up blocker turned off. Win 7 SP 1.
Any help would be much appreciated.
