If you drive away from the planned route recalculation starts as expected but it seems a bit slow to respond and the just gives voice commands to direct you back to the planned destination route. You can see your location on the map but the direction indicator is frozen at the last command and the redirection is not highlighted in blue on the map as per the planned route.

Now note that it sometimes shows the new route on the map. Just seems to hang or go slow to correct the map
