Another four-star review asserts the device looks small, but it is easy to see and isn’t so heavy that it falls off the windshield.
Additionally, one customer negatively remarks that after daylight saving time occurs, the time on the device does not update and is always two hours ahead or behind the actual time. Another reviewer writes that the Nextar GPS unit worked well initially, but afterward the power cord no longer stays plugged in and the battery won’t hold a charge longer than 45 minutes.
