I have a laptop that came with bt preinstalled. It is an xp sp2 machine and I use it to activesync via bt and it works fine. A gps that I am using works fine with my pocket pc, but when I try to pair with it using the bt setup wizard, I click on the device that the bt finds, but the next screen shows no services available, just a blank window. I have setup my bt on the pc to provide bluetooth serial port. What have I done wrong.
