My last post was short cause I was on my phone so let me clarify. When I had my Accent, I bought a used steering wheel with cruise controls. I swapped out the steering wheels but cruise control would not turn on.
Thinking out loud, but Hyundai usually doesn't do a lot of databus wiring. i.e. the steering wheel switches are probably discrete switches - if you are handy with a soldering iron, you could probably install the Hyundai steering wheel switches and the Rostra CC and solder the Hyundai switches to the guts of the Rostra stalk switch.I know I can always go the Rostra route, but it would be a lot cleaner if there was a way to do it with the factory parts.
