I always seem to be too slow on the first time or two when re-setting.

This works for me...

Position your finger on the button to the left of the speedo, turn the key to on(not start) and and push the button TWICE... bing bing, turn the key off.

Push the button in and HOLD it, turn the key to on again while holding the button in and wait for the beep. The display will reset.
