Thanks Blues Dawg. I had tried that a number of times, and had no problems in the past doing it. My service guy sent me PDF with instruction from the Tech manual, which had me do the same thing. NO LUCK at all. He told me to come up there and he would fix it in 10 seconds...I laughed!! but I do know him. After about 15-20 minutes he tried another trick, I didn't see in the manual. Its a 4 point turn. Stop your truck, press the normal buttons until the lines go in circle on your dash then pull forward straight, back up hard left, pull forward straight, back up hard left and so on until you have complete 360 degrees. That worked!! So if any of you are having trouble using the 360 turn, or just using your zone #...try the 4 point turn.
