I recently bought the above GPS secondhand with the sole purpose of using it for a cycling event. I loaded it with maps from Talkytoaster TT 1:50K Look n Feel Map which I loaded onto the Garmin 30x TT British-Isles Map loaded onto to PC and used within Basecamp I made my route and uploaded it to the 30x. The route appeared on the Garmin BUT when I went into the route options not all options were available specifically the reverse option?! Anybody have any idea what might be the issue?
