I had a PCIII on my bike. It broked down so now I ordered a PCIII USB. The question is like this. On The old PC3 you can upload maps with a PDA to the PCIII. Very nice and simpel as I live at 3:d floor and my girlfriend do not like to have my bike in the livingroom for maintenence. Bad girl. Is this possible to upload maps from a PDA on PCIII USB. I was looking in the instructions but I dont find anything. If it is possible do I need some special cables or adapters ?
