I have posted some of this already on the technical forum, but since it turned out to be a wish, I repeat it here:

I think it is very important for a car radio device to use RDS/TMC, at least the following features:
1) interrupt for traffice messages
2) information about the frequency changes and automatical selection of the strongest emitter available

As good the whole empeg is, the radio is really a mess. The tuner has no auto tuning, if I drive on a highway it doesn´t follow the frequencies of the radio station and the receiving quality is worse than in my girlfriends $200 Sony car CD radio.

Before implementing any more geek stuff I would be very pleased if this basic stuff would work.
