Hey team,

Sorry if this is a rookie question but I don’t have much experience with HRM.

I have a Garmin 920XT watch and got the tri bundle. Run/bike HRM seems to have bit the bullet.

I have a TOMTOM model SZ999 from a previous running watch.

I also have a Polar T34.

I have tried to sync them with my watch with no luck. Is this even possible? Or do I need to buy a new garmin one to be compatible with my watch?

Thanks everyone

Quinner
