Navman T1 RDS Traffic Module

Navman T1 RDS Traffic Module ... Traffic Message Channel (TMC) broadcasts real-time traffic and weather information via the FM Radio Data System (RDS). FM radio stations transmit traffic information updates on a regular cycle, particularly around rush hours, with up to hundreds of events broadcasted to TMC receivers. Your T1 will decode these events and send them to your iCN, which will then display the various events and give you options on how to avoid traffic congestion.
