I bought the unit, took it home, charged it up, turned it on, it works.
The following day I went to the golf course, turned it on. The unit found the golf course I Was going to play, but with another golf course info. Played with it trying to get the correct info, got frustrated and turned it off.
When I got home, I turned on the computer, went to the Golf Buddy website. Followed the instructions, plugged in the Golf Buddy and registered the unit.
The next day I went to the same golf course, and turned on the unit. The unit found the golf course and the correct tees, hooray!!!! I recommend registering the unit first.
The Golf Buddy works as stated. No monthly or yearly fees, and all my golfing friends want to use it, I have to take it away from them so I can use it. I Highly recommend this Unit.
Have used it at 3 golf courses in San Jose and 3 in Temecula, and it works great.
