This is what I did on my Tour:
1. Go to Options and then Status.
2. Once there type "test" on your keypad. You will get a message that says “To start testing, click start in the menu!”, and it will bring up the self test program.
3. A window will display titled “Device Self Test Application”
4. Click the trackball and select “Start”
5. Go down and only choose GPS and then click the icon / button marked Run. A screen will come up with some instructions. All I had to do was go outside and click the trackball and click "start fixing". It ran for less than a minute and give me the results, similar to the following:
GPS fixing succeeds!
Latitude: nn.nnnnn
Longitude: -nn.nnnnn
Course: 0.0
Address Info: null
Speed: 0.0
Extra Info: Valid Location.
Time to get auto fix : nnnnn ms
I then installed BBGPSGolf and tested it. BBGPSGolf actually displayed different distances and GPS locations as I walked down the street. I love it - can't wait to get to the golf course and actually use it!
