Traffic ... what traffic?
Traffic tie-ups can't always be prevented. But with Garmin's GTM 20, they can often be avoided.
Avoid Traffic Tie-ups
The GTM 20 is an integrated FM TMC (Traffic Message Channel) traffic receiver, antenna and cigarette lighter adapter. Designed exclusively for the American version of the StreetPilot c5xx-series, it receives digital information (where available) on traffic and road construction tie-ups that your compatible Garmin unit uses to offer an alternate route. TMC data, available in a fast-growing number of cities throughout North America and Europe, gives prompt, accurate notification of accidents, road construction, police, or emergency action, etc. - so you can visually monitor traffic flow and, if necessary, avoid traffic tie-ups.
Receive Real-time Traffic Data
In most areas, depending on the service provider, TMC traffic broadcasts are continuous - there's no waiting for scheduled traffic news updates or random alerts. With the GTM 20, you see traffic developments in real-time, as they happen, so you can make the right decision sooner. The system alerts you when a traffic problem is on your route and proposes an alternate route to avoid the incident. Because traffic broadcasts are received via a "silent" FM data channel, you can still listen to music or news programming on your car radio without interference from incoming FM traffic data transmissions.
The GTM 20 is a portable, all-in-one antenna, traffic receiver, and 12-volt cigarette adapter that does not require professional installation. It is included with the purchase of a StreetPilot c550 and can be purchased as an add-on for the StreetPilot c530.
