Hello everyone,
I have watched the videos and tried the procedures to calibrate the speedometer on my 2021 UForce 800 to no avail. Does anyone have the working procedure? I've tried the Hold the left button while turning on the key switch and holding both buttons while turning on the key switch and almost every combination of buttons and switch. I'm about 6MPH fastaccording to my phone GPS which adds additional mileage to the Odometer.. Thanks in advance!

Yeah that's a problem with the newer ones. There is a how-to video in the how-tos but it doesn't work for all apparently. The older ones were much simpler-just long-hold both buttons or hold both and turn the key on for the screen, change it, then hold both buttons to save and return to the run screen. 

I tried the procedure on the how to board and no joy. 22 800 trail.
