Trafc on Your Route
When calculating your route, the
nüvi examines the current trafc and
automatically optimizes the route
for the shortest time. If a severe
trafc delay occurs on your route
while you are navigating, the nüvi
automatically recalculates the route.
You might still be routed through
trafc if no better alternative routes
exist.
Trafc icon
If a non-severe trafc delay occurs
on your route, touch the trafc icon
to display a tab that shows how much
time the delay has added to your
route. This time is already included
in your estimated arrival time.
