Yep Tony, thats next on Marks (hot)list of things to do.

We have everything documented that Mark needs in order to provide Stalk mappings ala the IR mappings.

Once this is done, then any compatible non-Sony Stalk controller can be used by the unit to control it (or even slightly out of spec Sony Stalk Controllers could be used).

One thing though:
I'd check with the FAQ/developer section to make sure that the pin-outs/wiring of your existing steering wheel remote match that of the Sony Stalk controller (its (but don't quote me) a 3.5mm stereo jack, tip has Resister network value, middle has Shift value, ground has +5V on it).

Once this is done then Yes, it should work.

Of course, Mark actually has to do the kernel related stuff but I'm sure he can manage that within the next couple of weeks.

Right Mark?
