This sounds like an incorrect setting somewhere on the device, I beleive the routing options come under the profile menus on the touring series.
Routing Options
From the home screen, selectRouting Options
.
Routing Mode
: Sets the transportation method to optimize your route.
Calculation Method : Sets the method used to calculate your route.
Lock On Road : Locks the position icon, which represents your position on the map, onto the nearest road.
Avoidance Setup: Sets the road types to avoid while navigating.
Recalculation : Automatically recalculates the route when you deviate from the route.
Use gpx and not tcx, the gpx is more suitable for the edge and touring series.
Using the gpx will enable the device to calculate turns as opposed to arbitrary points as determined by the tcx. (not quite but near enough thats how it works)
