Hi,
I've had a good search and look through, but I don't think anyone's bought their GPS roof mount antenna before the GPS reciever like me! I have already bought a DAB/FM/GPS combined ariel, and I obviously need a GPS reciever to go with it, but I don't want the Bluetooth disconnecting all the time, so has to be USB based. Trouble is, all that I ever find are standalone USB units that don't allow an external ariel to be used. Oh yeah, its gotta be WAAS enabled and have any other new bells and whistles.
