OK, just spoke to the nice guys at
Suunto - apparently if you want to pair an extra
POD - Bike, Foot, Speed etc - you just select to pair it as another type of
POD.
So tonight I'll repair my roadbike as a Speed
POD. Apparently the T6c can recognise that it's actually a
Bike POD, and will allow calibration unique to that
POD.
(
Suunto advise lots of runners pair, calibrate and use multiple Foot
PODs as they use different shoes. the support guy said he was pushing to get this pairing trick included in the help docs)
I'll let y'all know how I get on.
UPDATE:
Yup, that worked. Again, you need to make sure that all other ANT devices (like your 2nd bike / HRM etc) are well out of range. Then it pairs up and cals just fine.
