GTM™ 20 Instructions

See the Important Safety and Product Information guide in the GPS device box for product warnings and other important information.

The Garmin ^® GTM 20 FM TMC Traffic Receiver receives Traffic Message Channel (TMC) information broadcast over the FM radio data system. When a traffic message is received, your Garmin GPS device can change your route to avoid the traffic incident. Traffic information is based on traffic data provided with the permission of one or more third parties. For coverage areas, refer to the Garmin Web site at www.garmin.com/traffic.

To receive traffic information, the traffic receiver must be connected to the GPS device and to an external power source, and the traffic receiver and GPS device must be in data range of an FM station transmitting TMC data.

NOTE: Garmin is not responsible for the accuracy of the traffic information.

Connecting Your GTM 20

1. Remove the vehicle power cable from your Garmin GPS device.
2. Connect the cable on the GTM 20 to the power connector on your Garmin GPS device.
3. Plug the other end into a power outlet in your vehicle.

1. Route the cable so that it does not interfere with vehicle operating controls.

NOTE: Heated (metalized) windshields could degrade the performance of the traffic receiver.

Connecting an External Antenna

An external antenna may be included in the product box to increase signal range. To purchase an external antenna, go to http://buy.garmin.com.

1. Connect the external antenna to the GTM 20.

Service and Subscription Information

The subscription activates automatically after your Garmin GPS device 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.

Using Traffic Data with Your Garmin GPS Device
