Last week my tomtom multisports started registering speeds as high as 180 km/h, even when I was riding aroung 10km/h. the error also affects the distance calculation that is way higher than the actual rode distance. Yesterday, I rode 41km (registered with strava on my phone) and my tomtom was showing 138km.
I have already reset my tomtom (Pressing down while connecting it to the computer) and it didn't help at all.
I wounder if there is anything elseI could do to have this issue solved.
Thanks in advance
