Does anyone who has an Decathlon EST-520 happen yo know how you reset the trip recorder? The instructions don't say (at least not to me) and Decathlon Manchester don't seem to know either.
I'm just going through the manual translating bits I can't work out (my French is useless). It says speed accuracy is +/- 2%. I haven't checked my new bike but on my old one it was reading about 10% fast compared to my Garmin GPS. I was hoping to find a setting to adjust that, but I guess I'm out of luck.
