2) "Route calculation error"; 3) "The route does not match the available maps. Cannot follow the roads precisely. Do you want to recalculate the the route?" Choosing [Yes] gives "Route calculation error. Maps do not have routable roads in this area." I ALWAYS get this on my Oregon 450 and GPS64 when I have updated my map. ie 1) I have previously routed from A to B using map M1 2) I update my gmapsupp to map M2 3) I switch on and select Recent Finds (or something like that) and click on the route which I created with map M1 I narrowed down the problem to the fact that map M1 and M2 have different map IDs and for reasons unknown but time will tell routes are linked to a specific map. I can still use the shortcut but have to move my cursor to a slightly different place and press GO. -- View this message in context: http://gis.19327.n5.nabble.com/Problems-with-routing-on-Etrek-20-with-latest...
