He is not able to use an SWI piece, he has buttons that he has or is building himself. There is a specific resistor value that the Sony joystick remote uses as a voltage divider network.

Exactly. If you could really measure the values, that would be great, thank you.

It will be Tomorrow or Monday before I can get you that info. 

Thanks. I have found a guy who makes these adapters and sells them for money (a lot less than SWI-JACK and such), he claims that the adapter works for Alpine, JVC and some other models, but he has not tested Clarion yet. He posted a schema in one discussion and he uses a Motorola microcontroller http://pavel.lajsner.sweb.cz/swc/swc-kx8.sch.png I am beginning to worry there will be more to it than just resistances..

New info again - http://www.avforums.com/forums/portable-dvd-media-players-recorders/248455-jvc-stalk-adapter-diy-2.html If JVCs are controlled digitally, there is a strong possibility that Alpine and Clarion will also be.
