Traffic Information
Using the built-in FM traffic receiver, the navigation system can receive and use traffic information. When
a traffic message is received, you can see the event on the map and change your route to avoid the traffic
incident.
Understanding FM TMC Traffic
FM TMC traffic receivers receive traffic information
that is broadcast over the FM Radio Data System.
The FM TMC subscription activates automatically
after your navigation system acquires satellite
signals while receiving traffic signals from the
service provider. You can add other FM TMC
subscriptions at any time. Check the Garmin
Web site at www.garmin.com/fmtraffic for other
available services.
⁄
• The availability of FM TMC depends on your region and
may require the purchase of a subscription.
Traffic in Your Area
When you are receiving traffic information, a
traffic icon appears in the upper-left corner of
the Map page. The traffic icon changes color to
indicate the severity of traffic conditions on your
route or on the road you are currently traveling.

Traffic on Your Route
When calculating your route, the navigation
system examines the current traffic and
automatically optimizes the route for the
fastest time, shortest distance, less fuel, or off
road. If a severe traffic delay occurs on your
route while you are navigating, the navigation
system automatically recalculates the route. You
might still be routed through traffic if no better
alternative routes exist.
If a non-severe traffic delay occurs on your route,
the traffic icon shows how much time the delay
has added to your route. This time is already
included in your estimated arrival time.

1
On the Map page, touch the traffic icon.
2
Touch Traffic On Route.
3
Touch the arrows to view other traffic
delays on your route, if necessary.
4
