i bought a new F955 and I can't install new software from the phone. Connect and the watch claims that the soft is up to date. Please help.
You can connect it to your wifi. It will only use it when needed.
Then force a sync by pressing the Light button (top left) and selecting the sync option. When that starts, swipe up on the screen or press the Down button (bottom left) to switch from Bluetooth sync to Wifi sync.
Wait a few minutes, then look in the Software Update section of the Settings menu. There may be an option to install the software update.
If this doesn't work, using Garmin Express with your PC might be what is needed.
