Bests & Worsts Reviews from Amazon

This unit replaced an older Garmin. It was easy for us to operate since many of the operations/features were similar to the old one. We received it the day before a long trip (around 1100 miles round trip). We were familiar with the route, but we wanted to give the unit a good test since we have several other trips later this year where we do not know the route. The overall features were good to excellant. However, the unit locked up once and it took us a while to get it back on line. The unit also randomly shut itself down 9 times, and it took several minutes each time to get it back on line. Since we knew the route, no problems were caused. But there are times where shutting down on it's own could cause significant confusion or problems. We sent this one back. I think a GPS has to be reliable, otherwise why have it (the first Garmin never gave us a single problem). .
