AeroPod, PowerPod and Newton

Hello!
Pease help. I have second PP. First one had battery problems. Now I can´t pair with my Garmin devices - Forerunner 315xt and 735xt. They just don´t see PP. I don´t have any additional sensors- speed or cadence. Is it involving somehow?
Tried everything I read in forums or homepage...
Any suggestions??

Before pairing your PP to your Garmin devices, you will FIRST need to pair PP to your speed and cadence sensors.

Until PP is successfully paired to a speed sensor, it cannot be paired to a Garmin.
