well i would give a go except the cable seems faulty. Power goes through just fine but no data, laptop doesn't even see the watch.... Tested the old garmin and that was fine as are other usb things.
Bit strange that a brand new cable is goofed.
oh well, Bluetooth it is then!
Did you install Garmin Express on your laptop before plugging in the 5X?
Only issue is that apps (downloaded on website) do not sync that way - if they had - it would be a killer feature for me.
