After connecting my brand new 700i to Garmin Express, it indicated that I needed system software and 2 map updates. I hit "Update All" but only the system update occurred. I tried again, hitting "Update All", but still nothing seems to be happening. It's frustrating that the app provides no notice that the press of the update button has been accepted nor is there a progress bar on the updates. If I hit "View Details", I'm given the option to update each map individually. If I do that, and progress through the confirmation screens, it eventually reports "there was an error installing the update" with no more detail. Any suggestions on how to resolve?
