the long forward and backward presses (scan forwards/backwards for next radio channel) aren't working for me either, regardless of whether I use the front panel buttons, the remote buttons or the buttons on my steering wheel remote.

It's nice to see the AF debug screen back - I quite liked it with whatever earlier version Peter had it in - but AF doesn't quite seem to be working right either. Sometimes it will jump to 88.something MHz and there is nothing sending on that freq.
