Route Planning, when it comes to the ride...

try doing your routes as courses instead of routes, routes mark the points you put and trys to use the gps getting you from one to the other so sometimes it wants to go a different way. Courses are like leaving a breadcrumb trail along the route so it follows where you want to go, you still have to put in course points and junctions and stuff to give you alerts

Thanks I'll look into that, not sure how it works though. I normally save a route in gpx, import it into the garmin and to follow it I go to "where to" I choose saved rides, select a ride then the options come up "navigate, map set up, copy to card". I select navigate. Not sure what the "map set up" option is for.
