ok. And how do you prevent the unit to recalculate? If I have to leave the planned route for one reason or another, I would like to be guided around the area that I can't go BUT I would like to be put back on the planned route as quickly as possible.
Is this not possible?
Maybe I do not use the route following feature correctly..;
Profile settings -> Navigation -> Routing -> Recalculation to change the recalculation settings on the 830. I would assume the 530 is similar. It should be in the manual.
If you want to be guided around a detour and back along your route you need to get a 1030 plus. Those capabilities are available in that unit. No other Garmin unit with navigation can do that.
