Well, I had this truck over a year and I'm just now finding out about this... also.. I was unclear in the video.. hold the OK button down for 5 secs. And keep it held down as you turn the key to Accessories .. also it makes your blinker chime a little off but the blinkers still operate correctly. Use at your own will and associated risks.. keep your eyes on the road, buckle up, follow the laws.
