There is at least one more TA issue, already mentioned before. The player doesn't switch back after a traffic announcement.

In my opinion it doesn't make sense to scan all the frequencies for traffic messages. But it should display a message if the user is out of coverage of the selected station or maybe select another station with TA automaticaly.

I'm working on a TMC (Traffic Message Channel) implemenation as a userland application on the empeg. Part of it is already working, but at the moment developing is pausing because I'm busy with other things.
