All of those are things I’m aware of and working on.
As of right now, the radio turns on when you press the HD Radio icon, and will turn off when you start playing music from within AutoSense. I could add a power button somewhere, maybe from within setup or something…
RDS data feeds in when the station is tuned, and currently only changes when new data becomes available. So it will retain the old info until overwritten. I play on clearing the data when tuning is changed, just haven’t gotten there yet.
As for being displayed twice, it’s in the HD Tuner fragment as well as the top bar. So if you go to the homescreen and such you still see the data.
Setup again doesn’t do anything yet. It will have power up volume settings, as well as treble and bass, and other things if required.
