Tee Selection has no effect on yardage

Just got my S60 and have not played a round of golf with it.  I live in a golf course community.  From home, I skip searching for satellites, select my home course, select WHITE tees, and the yardage on the first hole to the middle of the green shows 49 yards longer than actual.  All holes' yardage is longer than actual.  Selecting BLACK tees has no effect on yardage shown.  Am I doing something wrong?  Or missing a setting?  I updated the S60 with the latest software after I bought it.

Thanks,

Nick
