DMD2 2.99920 I am not sure if this is a “bug” or a “design feature”. . . . If I select a destination point on the map, and use the DMD2 in-built navigation function, it will plot a “public road” route and provide “turn by turn” direction. However, If I deviate off this plotted route for some reason (e.g. road works / crash / traffic, etc) DMD2 continues to update and show my exact position on the map, but does not re-calculate a route to my destination, or even show how I get from my current position back to my original route. << snip >>

DMD2 2.99921   Route re-calculation now seems to work, but for street / suburb / town use it seems to be very slow and clunky.   It will get me from town A to town B, but it is not the best tool for in-town navigation.
