Beginners Question for Traffic

I have a 720T that uses the RDS TMC Aerial. Is this different traffic info than that provided over GPRS. I have used this with tomtom previously.

The data comes from the same provider iTIS but the RDS feed is only regional where as the GPRS offers full country coverage. To be honest the regional coverage works fine as each "local" transmitter broadcasts large areas of coverage.

For example as I leave Blackpool I can see information from the North Lake District to Stoke on Trent and all the way to the East coast. As I drive further North or South a different transmitter is tuned in automatically offering data specific to the area I am in, you will receive this data long before your vehicle is actually within the area covered.

This Thread contains some additional information that you might find interesting, please note that when you plug in the RDS-TMC the GPRS traffic system is automatically disabled, the device can only use one source or the other - Mike
