Fil, just the man I was hoping would reply
On my 6630, I go to the bluetooth menu, then select paired devices. I have a few already like my PC ect. I go to add new device, select the GPS reciever, enter the passcode (says in the box), and then allow it (authenticicate it) to do things with the phone without asking me.
I done all this thismorning, and it still is listed in my paired devices!!
