OK, thinking about taking the plunge with the stock steering wheel buttons on my jeep. This link

http://www.wjjeeps.com/steering_btn_3c.jpg

shows what they look like, and as you see there are simple resistors in series with each switch. I have (5) functions available, up, down, center btn on left switch. And Up, down on the right one.

Question: can the resistance values the sony stalk interface looks for be set, or is it hard coded? I dont want to rip the steering wheel apart if I dont have to, but either way, anyone have thoughts on how to best map functions? Having not used the tuner yet, Im not sure what buttons do what in tuner mode.

I'm thinking right rocker = vol up/vol down (knob turn?)
Left rocker = <<, >> and the round button. I loose the down arrow, but for most things I could live with that. Radio mode?

Thanks-
Jeff
