I've searched this before and with a brief look again, I haven't found a solution or post relating to my question. Apologies in advance if it has been covered elsewhere.
I regularly get errors on speed, for example most recently friday night I went on the friday night skate in london (lfns.co.uk) and wore my Garmin 405. I have a maximum speed of 165,833.1 mph, see http://connect.garmin.com/activity/36503221
Is there a solution to this issue? Does everyone else experience this and do we know if Garmin are looking for a solution, assuming there isn't already one. Thanks.
