Garmin Edge 500- spurious speed readings when cadence is zero.
Recently, I see strange behavior with my Garmin Edge 500 (+speed/cadence GSC-10 sensor). When I stop pedaling (i.e., down a steep hill) the speed sensor goes haywire, reading out unreasonably high (45 MPH) followed by unureasonably low (12 MPH) values (whereas I know I'm doing about, say 20 MPH).
By coincidence (or not), I updated the firmware just a few days ago (from 2.6 to 2.7). Has anybody else seen this behavior? Is it linked to the firmware or is it some other problem, do you think?
