English is not my native tongue so may be I didn't understant all that you said. Your app all to scan frequencies. Is it possible to make an app that allow N900 to send a "RDS Eon" code to the car receiver. the goal is to establish a synchronisation between the N900 and the receiver to change frequency at the same time. Indeed, when i drive in surburbs there is not a lot of empty frequencies. Then I have to change manually frequency on N900 and my car receiver. It's not easy when you drive
