I have just come back from Sctoland using my pda (sat nav) and it worked really well. I mounted my pda in my tank bag as it was the only way i could make it waterproof. I put the pda in the map section and made hole threw the back into the main area of the tank bag, the holes were for the wires and the cradle to fit in. It also meant that all the wires and the satelite receiver were in the tank bag out of the way. To get power i bought a one meter 12v extension cable with a plug on one end which i changed for one that fits the bike and a socket on the other which i pluged the pda into, this meant that i only had one loose cable going to the socket. Using the original 12v plug from the pda it meant that pda was protected buy its original fuse, and it also means that now i am back it will go straight back into the car with no problems. The only down side was that with it being in the tank bag you have to look down to read it, but it didn't bother me and i found it to be the only way i could make the pda work, stay waterproof and on a cheap bujet.
