So, another niggle and a problem I also had on my Edge 1030. I have my Quarq DZERO powermeter connected by Bluetooth and 'Calibration Prompt' enabled.
Whilst the powermeter and Edge 1030+ connect straight away on power-up, I am never prompted to calibrate my power meter. However, if I connect via ANT+, then I do get a prompt to calibrate.
So, you'll all say I should use ANT+ which is fine, but it still doesn't avoid the fact that there is an underlying problem here.
