Yes I have used your web sight. Thank you.
I have loaded City Nav maps onto my sd chip inside the gps. They show up nicely. Now I only have to download routes and waypoints.
If I page to a map and hit menu, I get several choices. Recalculate is there but is always greyed out.
If instead, I reach the map page by selecting a saved route and then chosing map instead of navigate, then I get only 2 choices. One of the choices is "map set up" but I can't find anything of use there on any of the tabs - certainly no "recalculate".
When I chose navigate instead of menu, it calculates quite a while but only comes up with a distance between where I am now and something on the map opened by my route. The route I hoped to recalculate remains straight point to point.
The manual only talks about recalculate while talking about building a new route on the gps.
Did you suceed in loading up routes that followed the roads for your trips?
