wilkes

I just upgraded to a Motorola Razor cell phone. It has blue tooth. I have been trying to link it up with our TomTom one GPS. which is supposed to be blue tooth capable. I can't get it to work. The GPS. says the phone can now be used but it does nothing when I make or recieve calls. The instructions that came with the phone and the GPS. are so vague they are no of help. Anyone have any advice ??
