I had a thought while I was looking over the components I'm planning on getting for my truck (some day). I know basically how a steering wheel control interface works. One thing I was wondering was, does it affect the controls for my DIC? I'm not exactly sure how it hooks into the steering wheel control wires, so I wanted to make sure I would still retain the use of all 4 buttons for my DIC controls. Anybody know? Thanks! P.S. If it matters, I have no XM, Onstar, or Bose.
