Service and Subscription
Information
Depending on your region, your trafc
receiver receives trafc data through either
a premium service or a free, public service.
For information about your trafc service
subscription, see the product packaging or
the Trafc settings in the GPS device. The
subscription activates automatically after your
Garmin GPS device acquires satellite signals
while receiving trafc signals from the service
provider.
You can add other FM TMC subscriptions
at any time. Check the Garmin Web site at
www.garmin.com/fmtrafc for other available
services.
Before mounting the trafc receiver, see the Important
Safety and Product Information guide for information
about laws pertaining to windshield mounting
