I have a 2015 Ford F350 that I changed the tire size on, went to a 295/75R20. The change actually affected my navigation to the point of being worthless. I'm told that Ford engineers designed the GPS to use dead-reckoning in conjunction with satellite, a change in tire size throws your location for a loop. This system not only put my MPH dead on, it also fixed my Nav. issues. I would also recommend leaving the data cable attached for easy future adjustments. Great product!
