What do you mean, the pinout or the physical plug? I was citing a URL for
the pinout.

Don't look for a changer, you need the radio. The Archos becomes the
changer.

Very likely.

No, it's more involved. Don't forget that the changer protocol is
bidirectional, we need to send, too. And then I want specific timeouts, etc.
In fact I do the receiving with the UART feature of the CPU (generating
interrupts, so I don't have to poll) and the sending by setting pulse edges in a
timer interrupt.
