I have a new Garmin 530 with a speed sensor 2, software updates within the past few days. IT seems on the 530 they took away the manual wheel size calibration. I've looked through the manual and there is no mention of it. I've looked at the forum questions where they suggest Settings>Sensors>[speed sensor*]>sensor details - there is no listing of the wheel size there, only that it is synced through ANT+, nor does there seem to be a wheel size anywhere else in that menu heirarchy.
Did Garmin remove the ability to calibrate the wheel size on the 530? Is it something they did specifically for the speed sensor 2 (iow if I use a different ble or ant sensor, might the option show up)?
* On my unit the speed sensor shows up as SPD- (numerical ID)
