That's all fine and dandy it you stick to that setup, the GPS is great for those of us that like to tinker. I've had 3 different transmissions (2 of which were OD) and 3 different set of gears in mine within 5 years and am about to switch rear tire size too, it was a good investment in my case.I put the correct speedo gear in the trans. Factory speedometer is +/-2mph with my phone GPS.
