Anyone know where I can find the settings on the factory Nav unit to change the bass and trebble and all that I have been through every screen I can find and no luck. I can't find the book that came with the truck about the nav system so I am stuck.

the lower dial on the right side. Push it in, then push again untill what you want to adjust is highlighted.

Yes. It will also have a little square on there where you can adjust fade, and balance. Just move it over to where you can adjust bass, mid, and highs. It looks like a little three bar equalizer.
