I'm not sure whether I have the old or new sensors (Edge 510 if it helps) but when I turn off the GPS I get speed and cadence data just fine.
GPS is off, i've used the old sensor for years but got the new one because it looks much better. Anyway noticed that there were big peaks and troughs on the speed plot (bigger than the small ones on previous sensor) I contacted garmin customer service about this thinking it was faulty and they asked about usage etc and when i mentioned i was using it indoors at the velodrome they said this was to be expected if the banking is steep - they didnt mention why but presumably the accelerometer doesnt work as well when it is tilted.
It still measures speed and distance it's just not as accurate as the old one.
