Gerald,
I am sure your Bluetooth set up works well, but doesn't the Bluetooth
receiver need a battery? Or does it have to have a power supply?

I have a CF GPS - A Globalsat 307. I have an external antenna, but it is
just not needed. This unit gets a fix using it's built in antenna when I am
at my desk inside my house and not even near a window. Same is true in car -
It works well anywhere you would be likely to put it, without the external
antenna.

This did not really surprise me, because even my old Magellan GPS 3000 would
work in my car without the external antenna, so long as it was set on the
dash with a view of the sky.

The CF GPS cards do drain the PPC battery, as do most add-on cards. I
usually have my iPaq externally powered from car or boat. For portable use,
I have a sleeve that has two CF slots and an auxiliary battery - These
Mempad sleeves are a great buy at $79.00
