Hello and thnaks for this great app.
I've used it today for the first time and was very satisfied with the result.
I have one sugestion/question:
I don't know if n900 fm transmitter has the capability of sending the TA signal.
According to wikipedia RDS defenitions (http://en.wikipedia.org/wiki/Radio_Data_System)
"
...
TA, TP
Traffic Announcement, Traffic Programme The receiver can often be set to pay special attention to this flag and e.g. stop the tape/pause the CD or retune to receive a Traffic bulletin. The TP flag is used to allow the user to find only those stations that regularly broadcast traffic bulletins whereas the TA flag is used to stop the tape or raise the volume during a traffic bulletin."

I think that this funcionality would be a great enhancement.
Thanks for tha app.
