The simple plug-and-play interface lets you easily connect the device to your compatible Garmin GPS (replacing the existing power cable for your compatible Nuvi). Traffic broadcasts are received via a "silent" FM data channel, so you can still listen to music or news programming on your car radio without interference from incoming FM traffic data transmissions. Traffic developments are displayed in real-time, as they happen, so you can make the right decision sooner.
This service is free and is currently operational in Brisbane (including Gold Coast), Sydney, Melbourne, Adelaide, Perth and Canberra regions. (Check Suna Traffic Coverage for more information.)
The once off price for this traffic receiver allows you to get lifetime traffic subscription through Suna Traffic channel. There are no subscription fees for use of this service.
