I have connected my Garmin Nüvi 2597 to my MacBook to update through Garmin Express. I have unplugged the device and connected it as instructed. However, it does not proceed to the next 'Prepare' step even after some time, and simply gets stuck at "Step 2 of 4: Restart Your nüvi 2597". I have repeated the process without any success, while when I tried to restart Garmin Express I get the message "If you quit Garmin Express while updating or syncing is in progress, your device may not work properly and/or may lose data". Can someone please tell me how to proceed?
