Since a few days I have issues with my Garmin Edge 520. During parts of the ride it registers speeds between 60-115km/h and also calculating longer distances. The location of the registered courses is correct, however.
At my last right it occured for about 40 minutes (total ride is 5 hours) and the ride before that it occured just after 1:15 hour, until the end (total 2:16 hours). The registration of the right is totally useless and all segments are trashed. I don't know what's causing this issue, hopefully someone can help me.
I'm using the Garmin Edge together with a speed sensor, power meter and heartrate sensor.
