Forerunner 945: I have paired it with my Bluetooth earphones ok but the volume controls do not work on the watch. The volume seems set by default at 100% and is deafening! (there are no volume controls on my actual ear phones so the setup is not usable). My ear phones are BT v5.0 ( myinnov-x10 ) and work perfectly with my Iphone and other devices. I welcome any advice. Note the other music controls (like play/pause/previous) all work ok - it's just the volume on the watch that is the issue. When I press the buttons I can see the press being registered on the watch (+, - signs highlight at each press) but the headphones do not get the signal.
