Product Specifications

When it comes to avoiding traffic jams and bottlenecks, good decisions start with good information. And that's where Garmin's GTM 10 traffic receiver can make a quantum difference in any driver's quality of life. The GTM 10 is a small FM-band traffic receiver that connects with a car radio/antenna system to provide real-time Traffic Message Channel (TMC) data to compatible Garmin GPS navigation products - which then depict and identify problem areas on their moving-map displays. Available in a fast-growing number of cities throughout North America and Europe, this TMC data gives prompt, accurate notification of accidents, road construction, police, or emergency action, etc. - so drivers can visually monitor traffic flow and, if necessary, select an alternate route. The TMC traffic alerting system works on an FM sideband signal, which utilizes RDS (Radio Data Service) technology. Digitized and coded real-time traffic broadcasts are received via a "silent" FM data channel - which means that drivers can still listen to music or news programming on their car radios, without interference from the incoming FM traffic data transmissions. 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 10, you see traffic developments in real-time, as they happen, so you can make the right decision sooner. The system will alert you when a traffic problem is on your route and propose an alternate route to avoid the incident. The Garmin GTM 10. If getting stuck in traffic is not your idea of fun, this is the technology for you.
