Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
With the steps you have done, considering your golf buddy can turn on and work normally, then your issues with syncing and connecting have to be due to a bad usb cord. You can get a replacement here.
Now, if your golf buddy cant turn on or work let me know, as that means the issue is something other the the cable.
