GPS on the NX70

[bassboy_pete]

Hey guys, I am looking to get a GPS reciever for my NX70. I prefer it as an expansion card. On Ebay, I saw people selling CF GPS. Will those work on the NX70? If not, link me to a place that sells them. Also, is there a problem with drivers at all? Do I need special ones? I don't know anything about the GPS on this model.

Thanks
