I have been using .gpx to upload created routes into my garmin nuvi 780 and then playing back those routes as i bike. However i can't seem to get the sound to work. When i upload the route and ask to get navigated to the starting point of the route the gps gives me turn-by-turn directions. Yet, once i start the .gpx route it doesn't say a word. Is there anyway i can import a .gpx route into basecamp and then import it to my gps so i can still get turn by turn directions along the route?
