I'm having some issues adjusting my speedometer. I've adjusted my N/V Base and Tire size, but I see no change on my speedometer read out vs GPS speed.

Its still off a solid 5%. Maybe I'm missing a setting. There are also no options under controls and special functions in the VCM scanner.

Is something wrong or am I missing something.
