Hi, something weird has happened with my golf sports watch. Ever since I started using it I have had no issues finding my home course. Now it suddenly does not find my course. The watch buzzes and presents a blank screen. All other golf courses in the vicinity are found but mine is no longer there. I have 'Reset' - not factory reset it and still it does not find my course. It is up to date and syncs properly with my PC. Any thoughts?
