We purchased the Good Sam GPS several months ago. I used it locally for awhile and it worked fine. I am just back from a 4500 mile trip in our small class C. I loved the multi-stop trip function.
That said, the unit has several glitches: 1) Whenever we stopped for gas, etc. say our next direction was 10 miles ahead, when we got back on the road it started to tell us to exit or make a U turn. 2) Traveling to major cities on the main highways it continually kept telling us to get off and routed us through smaller towns with traffic. 3) On smaller roads it seems to get lost. Near Crater of Diamonds State Park it wanted us to backtrack 30 miles rather than go 15 miles direct to I-30. 4) Speed limits quite often were different than those posted. 5) It often sent us on a circuitous route. Headed for a northern suburbs of Dallas and approaching from the NE, it routed me through downtown Dallas. Fortunately I knew the correct way at that point. Figuring that I needed to adjust the settings so I selected that I prefer freeways. With this setting, on a 15 mile trip that I was familiar with as an experiment it took me 5 miles away from my destination through traffic to the freeway so it was 25 miles and an additional 15-20 minutes. Not really sure what setting to select to minimize these issues.
Obviously we need to consult a map and plan our route in more detail rather than relying completely on this unit. We have a Garmin RV unit that we use with our truck hauling our trailer. We've had a few issues with routing, but nothing like with this unit.
