Tacx Neo 2T re: Cycling Dynamics, Garmin and TrainerRoad

Hi - the Neo2T supposedly offers this with a paired head unit. Neither my Garmin Edge 820 nor SRM PC8 can see any cycling dynamics - only L and R balance. The latest firmware on Neo 2T permits Ant+ display of both. Speaking to Garmin seems the Neo 2T is a defective unit oh well. If anyone has any ‘tricks or tips’ or have actually gotten this to work (cycling dynamics on 2T) let me know?
