Garmin DriveAssist 51 locking up
Ever so often my DriveAssist 51 will simply lock up while driving. The map display looks the same but it is just frozen. A hard reset by powering of the unit fixes it and it returns to the current route. I have updated all software, maps, etc. I have tried it without connecting the smartphone app (I have an iPhone) and it has locked up both ways. It does not happen all the time, but it is starting to get frustrating. Anyone have any ideas or fixes?
