Tap this button to change your route so that it passes a particular location,
perhaps to pick someone up on the way. When you do this, a marker is
shown on the map for the location you choose the travel via.
Travel via...
You choose the location you want to pass in the same way as you choose a
destination. So you can select from all the same options: for example,
Address, Favourite, Point of Interest and Point on map.
Your GO will calculate a new route to your destination that passes the loca-
tion you chose. Unlike your final destination, your GO does not inform you
when you pass by this location.
Using this button, you can only travel via one location. If you want to pass
more than one, use an Itinerary.
Tap this button to return to the original route without deviations to avoid
roadblocks or travelling via particular locations.
