Tech Specs
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 is 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 will alert you when a traffic problem is on your route and propose an alternate route to avoid the incident
Mounting: No permanent installation required. Adapter plugs into 12-volt cigarette lighter, supplying power and traffic data inputs to compatible Garmin GPS car navigation systems
Interface: Connects to GPS device via 18-pin flat plug
