Thanks Al
I finally found the app for use on my android phone, but can't find the connection cable etc.

When you set the wheel dimeter do you use the circumference around the outside of the tire,
or across the tire diameter?

Sorry I'm late to this conversation, you're controller programming settings or firmware must be what's preventing you from changing the wheel diameter from the display settings.
Whenever you are able to access the programming software and change the wheel diameter, the most accurate selection is to measure your rear tire's actual circumference in inches, then divide that value by 3.14159 to get the correct wheel diameter for the most accurate speedometer calibration.
Lay out a tape measure up to approximately 100", then rotate your rear tire until the valve stem is directly at the bottom (6'Oclock position), align the tape measure end with the valve stem, then sit on your bike (tire deflection from your weight will affect the diameter slightly) now roll forward one full revolution, until the rear tire valve stem is back at 6'Oclock, and note the corresponding value in inches on the tape measure. My 27.5" x 3" tires circumference measured 90.5" which calculated to 28.8" diameter, I set my display and programming settings to 29" diameter and compared to GPS readings, the speedometer is very accurate.
