Summary: The GPS unit seemed to be a good value and worked well for a test drive. However, many attempts were made to download the Garmin/Express software and all attempts failed. Without that software download I couldn't register the GPS and most likely would be unable to download map updates. The tech support group had suggestions, but no solutions to my issues so I had to return the GPS. This was very disappointing because I was trying to replace an older Garmin unit.
