I received the unit and had to sign up and pay for membership before I could see the courses that are available on Sonocaddie. The majority of courses I play were not on the list. I found out how to get courses mapped, if the scorecard doesn't have a sketch of the holes on it, they request you go to Google Earth, send to the Pro of the Golfcourse, have them number the holes and mail to their mapping company. One of the courses that was on it was wrong, I was on a Par 3 and it showed it was a Par 5. If you accidently get on a course that is on it and right, then it's great. If you need to contact Sonocaddie customer service, good luck, answering service after 3 pm. What a waste of time and money. It might explain why so many, including mine are on ebay.
