Hello friends!
I have a 520 Plus, the device is connected with HR sensor, but not show the value on display. The sensor is Magene, not Garmin, but it works 3-4 months ago. I connect the Magene HR sensor on Garmin 520 and it works pefectly. I think is software problem, but i don't know how can i fix this problem. The version of my 520 Plus is 5.70.
Anybody have an ideea? Thank you.
