Garmin 3790T
While downloading the recent map update Windows 7 64-bit suddenly failed to recognize the Garmin unit and the download process froze. I unplugged the unit, replugged it and the 3790 was again recognized. I restarted the download and after a few minutes the computer again dropped the USB connection and the process again froze. Repeated the unplugging and re-plugging but this Time no recognition. I have another Garmin unit, different model, which is recognized by the same USB ports. Garman Lifetime Updater
search finds no unit. No unit visible in "my computer" or "computer management" . Attached to my laptop same problem no recognition.
Any suggestions appreciated. Thanks
