Update - I downloaded a huge map update about a week ago. The issue with speed limit accuracy seems to have been corrected. Rand Mcnally also made a number of other software upgrades. For instance, split screens at intersections, etc.
Today, we were in Pueblo, CO, and decided to check out potential camp grounds in the area. We used the GPS database to locate some, and had it take us to them for future reference.
We're very pleased with the Good Sam GPS overall.
