I have a Fenix 5x plus & old half dead HRM RUN strap which has served me well for years
HRM 600 after having HRM Run (with advanced metrics) is a joke lacking backwards compatibility with older devices which function fine with the older advanced run metrics. I bought this for Christmas and am very frustrated and disheartened by Garmin on this product, it has made my running go backwards??? What are the chances they will fix this for the older watches like Fenix 5x plus etc?
