I am about to buy the 700w. I had a Dell Axim x51 that I had a Pharos wired GPS receiver and Ostia software. I would like to reuse my receiver and software on the Treo 700w. Does anyone know where I could get the serial cord that would go from the bottom of the 700w to my Pharos GPS receiver? I am also thinking about buying the Seidio G4500m car cradle that charges the 700w and also has a speakerphone in it that has what they call a RJ-11 connection for plugging in a GPS receiver. Does anybody know where I can buy that cord?
