I bought Nikon Coolpix P6000 recently and was disappointed that the GPS features did not work.
 I tested the GPS for 1 hour on the way home from the shop by placing the camera on my car dashboard but there was no updating of coordinates.
 The following day I tested again the unit for another hour on the way to office by placing it on the car dashboard and still there was no sign that the GPS pick up any signal.
 Just to give Nikon another chance , I went to a big lake near PJ and left the camera in an open area at the lake side for 15 minutes and but still no sign that the GPS is alive.
 Frustrated, I packed the camera and just took it Nikon service centre .
I had used garmin Mobile with O2 phone , Garmin 60CS, Nokia N82 before and never experience such problem .All these new unis just work within less than 10 minutes. And I was looking forward to buy GP-1 for my Nikon D300 but now I am not sure if Nikon is very serious with geotagging or whether it was pure marketing gimmick.
Drop me a line if you have the same problem.
