Broadcast HR to Keiser 3mi. Anyone have this setup?

M3i not 3mi....

Sorry if this is answered somewhere else, but I tried several searches and couldn't find an answer.

I have the Fenix 5x. I have never tried the HR Broadcast before. I just had Hip Replacement surgery and I'm borrowing a Keiser M3i to assist in rehab. All I can find on the Garmin site are the steps to Broadcast HR to other Garmin Products. All I can find here is this... https://forums.garmin.com/forum/into...e-on-treadmill.

The Keiser manual seems to only allow a Polar strap HR to sync with its computer.

Is Garmin proprietary only to Garmin?
Is Keiser proprietary only to Polar?
Is there anyone out there that has a Garmin and Keiser playing nice?

It's really annoying that all these companies claim to be great and friendly.....except to each other.

Thanks for any help.
