Have an '04. Found a way to disable the lockout feature when driving so passanger can play with the Nav system. Problem is, the workaround I found is for an FX- That box is under the front passanger seat, thus easy to get to. Was wondering if anybody knows EXACTLY where the box is located and what to remove to get to it. (Need to get to the back of the box where the 28 pin connector is located) If I find out where it is and I'm sucessful with the mod, will post all details. Oh, I'm new to posting anything. Hope I'm doing it right!
