I just bought an '02 Jetta. First, I was wondering if it's possible to remap the volume and track buttons on the steering wheel to serve some function to the Rio. The other thing I was wondering is if any of you had bought any of the custom lenses and if so, which one looked best with the Jetta's purplish dash. I know there's a lens comparison chart here but I'm looking to hear from someone who's actually seen the custom lens in their car.
