Just fitted a speed/cadence meter to my bike and paired it with my Garmin 310XT watch. When trying it out (stationary with no GPS signal) I was getting a speed indication based on wheel speed. I haven't entered a wheel circumference into the watch and can't find anywhere to enter one so how can this be accurate? I thought the speed indication would still have been obtained via gps?

In reply to Alan.T: I believe it self calibrates, i.e. it compares the reading from the cadence sensor to the gps readings when actually moving, so shouldn't need manual entering of a wheel size.

The procedure if it's never been taken out with the cadence sensor on, I'm not sure - maybe it assumes a default value.

In reply to Alan.T:

Have you ridden outside with the GPS turned on? If so then it has automatically determined your wheel size - or it will next time you ride outside.

Otherwise:

press & hold mode to select bike mode.
press mode > settings > bike settings > bike name > bike details >

select custom in wheel size field if you wish.

I've always just left my Garmin on auto calc.

Ok, thanks for that, found the bike details and it is in auto with wheel size showing 2100mm. This must be a default setting as I haven't been out on it yet with sensor fitted. Will check it changes after a ride.
Cheers
