4 GTM 20 Instructions

Testing the Trafc Receiver

Check the Map: Check the map on the GPS

device for trafc incidents or a trafc icon.

Refer to the owner’s manual.

Verify Signal Strength: If you are inside a

garage where radio signals cannot be received,

drive the vehicle outside.

Verify that you are in a service area: Check

for service from the pay service or free or

premium services.

Service and Subscription

Information

Depending on your region, your trafc receiver

receives data through either a premium service

or a free, public service. For information about

your trafc service subscription, see the product

packaging or the Trafc settings in the GPS

device. The subscription activates automatically

after your Garmin GPS device acquires satellite

signals while receiving trafc signals from the

service provider.
