I created routes in Basecamp and then copy & pasted the routes into the internal memory of my 2460. After restarting the 2460 and entering "Trip Planner" I get the hourglass as the routes are converted into the 2460. After the routes are converted I can access and use them on the 2460 but when I connect the 2460 to my computer I can not find the routes with File Explorer. Where are they?
