The only way I could get the Terraserver maps to correctly match up with tracks and waypoints was to first convert all waypoints to UTM. This does however introduce some difficulties. Polar regions as I understand are outside of the UTM range, and currently UTM zones are not supported. That is, you are either in one zone or another, and you cannot switch by simply panning the viewport. If you have data which is in more than UTM zone this will most likely be a problem.

Also, only Terraserver (Topological and Aerial) maps are currently supported. This is mainly because they were the only maps I tried that I could figure out how to download them. Terraserver maps are only available for the U.S.
