Garmn speed/cadence sensor disabling gps?

[Runbikeswim]

On my garmin fenix i want to use a garmin speed /cadence sensor ( just the cadence part) but seems it disables my gps as when i record a session the distance stays at 0?

 

Any advice? I presume its cos the speed magnet is not on and device sees me as standing still? How do i disable this?

Set it up as a cadence sensor and not as the combo?

No such option

Little confused here. Why not just add the magnet?

 

Don't think you have the option to split the speed censor and cadence option.

Not to high-jack this thread, but it also involves Garmin products.

I have a Virb camera and a Garmin 800 cycle computer.

If I mount the Virb on the handlebar next to the 800 on the stem and switch Virb on to record, it also disables my 800 GPS.

I then mounted the Virb on my helmit  and the 800 works fine.

Could not figure that one out.......
