I have bought pre owned GARMIN FENIX 3 HR and i have trouble connecting it to garmin express or garmin connect to my Iphone XS IOS 13.
For garmin express on my pc I can't add device because ID no valid, and on my mobile at first i would not connect/pair with the phone because of an error 400 google http: something and then i have tryed to connect to other Iphone and it connected but now when I have tryed on my phone i get the same ID not valid try to contact garmin support.
I don't know how long would it take for gramin to write me back with some info about my problem and it realy bugs me that i can't use the watch in full capacity.
Updated watch manual to news frimware 5.31.
Any HELP ?
