I've not been able to set up this watch from day one

  1. I haven't use my forerunner 55 for 3 months.
  2. Now I cant reset it & sync it.
  3. I changed the watchface when i first got watch, now can't change it back to its original face.
  4. When I try to sync, it says turn on Bluetooth, it's on!
  5. Just going round in circles.
