Motorola V500 / V525 / V505
Usb connect question
I use a Macintosh and it syncs flawlessly with the address book and calender programs I have. The Bluetooth also syncs flawlessly with the Powerbook but only audio, video and photos.
In addition you can use this cable to dial from your internal modem for Internet connection to your computer.
I don't know too much about PC's, but I would assume Motorola sells the CD & USB cable together as a package so you can do the things the Mac does automatically. I believe the whole package is 39 USD.
