Il mio Pocket ha sia la SD, sia la CF, e quindi non ho problemi, ma non si sa mai per il futuro... anche perchè non mi piacciono molto i ricevitori Bluetooth... sono sempre scarichi quando servono... 
It's a GPS receiver which will plug into an SD slot on a device... what's cool though is that you can also put into it a MicroSD card.
This is a real bonus as if your device doesn't come with GPS then you can use the GPS and have the maps stored on the MicroSD card (which are now available up to 2GB)
You can check out details over at the Spectec website
