How to change speedometer from metric to yards?

1 comments:

Mr. Anderson

May 19, 2025

The EDT EX-RAY speedometer does not support changing the unit to yards. It allows switching between miles per hour (mph) and kilometers per hour (km/h) only. To change between these, enter data mode, wait for "M H" to flash, then press the button to toggle between mph and km/h.
