User positions main use was to save locations of know speed traps/ mobile photo radar units.
I personally use my unit for 2 other uses so far.
One for a turn on the highway I have often over shot to a friends house I do not go to that often.
Another for my friends cottage, hes off a main road and there is no signs marking the turns. Anyone who travels to friends cottages will find this feature very handy, my vehicle is equiped with a built in navigation system however when i save to that unit, there is no audio alert as well saving locations isnt fast like NavAlerts simple 1 button operation.
