Now what??? Bad update, or what?

I've had problems off and on with this expensive golf watch...  It's been relatively OK recently until today.  The last update obviously hosed something...  For instance, I was standing with one foot on a green that the watch said was 65 yards away... This after the last two holes were also WAY off regarding yardage.  I started using a FREE app on my phone that was much more accurate than my $500.00 watch...  WHY!!!???   Also, when I'm done with a hole and I've walked away I USED TO be able to click on the pencil on the bottom of the watch and input my score.  Now it often shows me the caddy and asks if I want to check again... I had a decent round today that was totally RUINED by having to deal with this stupid expensive piece of equipment.  Was the last update a clinker???  If not... WHAT THE HELL IS GOING ON!!!!
