Looking great so far!

Q1: How do I turn it off again?!! Pressing STOP takes you out of the radio
screen, but the radio keeps playing. If I play an MP3, the radio is still
playing, and the MP3 never appears, although the WPS comes up!

Q2: I have heard it expressed about the Archos radio that the frequency
tuning is not fine enough. I see you tune up/down by 100000 (0.1Mhz), but
is this your choice, or a hardware issue?

I'm sure there will be other questions, and I appreciate that this is a
first pass/proof of concept.

Other items for the list (not necessarily to be coded by you of course!):

1. saving and naming and re-ordering favourite stations. At least 10
favourites, but maybe as many as 30, or even unlimited. This would need to
be stored to a file rather than in ROM. When tuning manually, display the
saved details if they match the current frequency.

2. auto-scan feature - search for the 10 strongest signals and store them
in a temporary "playlist" - handy for people on the move, and often seen
on car systems.

3. rds/eon data. I know we have this in the UK, but no idea about other
locations. The radio station transmits extra data embedded in the signal
which carries station name (so you can display it automatically), a flag
when traffic info is being transmitted so you can switch from MP3 to local
traffic info, and I think even current track info (artist/track name).

4. Auto-resume - remember the last frequency played, and resume at that
frequency when returning to the radio. This could be stored in ROM or on
disk.

Some of these may be impossible due to hardware limitations of course.
