HRM pro plus chest strap replacement

Hi everyone,
I have a Garmin HRM-Pro and the strap has completely deteriorated (the rubber layer peeled off and the electrode material underneath is damaged).
I’m trying to understand whether the strap on the HRM-Pro is replaceable.

Does anyone know for sure:

  • Is the HRM-Pro strap replaceable at all?

  • Has anyone managed to replace it through Garmin support?

  • If the strap is damaged, does Garmin usually replace the whole unit?

Any insights or experience would be very helpful.

Thanks!
