From: Meyer, Stefan (empolis GT) (stefan.meyer_at_empolis.com)
I read your last mail about the sony car stereo. Do you know how to connect
the Jukebox to the sony ? Is there any way to make an adapter to the changer

When should rockbox send data and what should it send then?
It could send the whole WPS every second (to have updated track
time) or just the song title each time a new song starts.
Somebody wants to build a remote with a complete copy of the
rockbox display for the car for example, somebody else wants
to display the song title only.
Transfering all available data every second is much data and
not needed in most cases. If we introduce a system to choose
the data to be transmitted, it is the most simple way to
frequently poll the data.

That's no problem when the remote polls the data.

This is no problem. If we have one working solution, we can
program the controllers to (almost) everything we want.
I'd like to have one translator for my Sony car stereo, too.
But for a normal remote, I prefer to have one piece only that
needs to be carried around and wants to have batteries.
