Hi all, I have recently lost the external receiver I use with mobile geo. I am currently using another external receiver but found it isn't as good, even though it is along the same make similar to the receiver that came with the mobile geo phone. Just wondering for the time being, how do I switch back to using the phone's internal receiver and how do I know for sure if the internal receiver is being used? Many thanks for any help, Happy Christmas, God bles, From Andrew
