AeroPod, PowerPod and Newton

I'm trying to pair a PowerTap with iAero GIII to do some comparison riding. I'm at the wireless config screen (ON) speed (FIND) cadence (NONE) HR (FIND) and then...nothing! Once I hit the center button after HR (FIND) it's supposed to go to Pin which I'm supposed to set to "FIND" but that option is not there.

Is there an option in iB3 software I need to enable first?

Thanks

An update to this problem (Thanks for the help from VeloComp!)

1. My iAero was actually programmed as an iPro, so I was not getting all the functionality I should have had.
2. The PT Hub I have is not (yet) ANT+ Sport compliant. The CPU is ANT+ SPort compliant so it receives the iBike speed/cadence signals. I am updating the firmware on the PT Hub to make it ANT+ Sport compliant.
