Had anybody yet an idea to decode the "Traffic Message Channel" of the RDS system? (see http://www.tmcforum.com/)

With TMC traffic alerts are transmitted in the background and anytime, so traffic alerts would be available all the time, not only once or twice per hour.

This would be extremely helpful, especially if included in gpsapp so that traffic alerts on the actual route are displayed automatically.

Anyhow, the page has flash. Ew.

I once started a TMC implementation on the empeg.
The lastest version I made prints out the undecoded TMC messages. This works well.
But I never decoded the messages, even tough I have a decoding table at least for switzerland.
Search for TMC on this board.
