Using 8330 with external GPS

I have seen this discussed in several threads but I have not been able to find specific instruction on how to.
I have a Blue Logger Bluetooth GPS puck that works fine with other devices but I cannot get my Curve to connect to it.(it does discover it) I would like to be able to use it with Google Maps. My BB maps works just fine but I would like to use the satellite view in G'maps.
Can someone give me some clues on how to set it up to work with an external puck please.
Thanks,
Julian
