Audiovox CDM-9900

Can anyone help me locate a data cable for this phone? All I want to be able to do is transfer back and forth my phone book and pixs from the cell phone to a laptop. I know someone had mentioned about a data cable you can purchase from Radio Shack, but when I went to my loca Radio Shack store, all I got was blank look on their face, no one seemed to have a clue as to what I'm talking about. Please let me know what I should ask for, i.e., model/name, etc. Any help regarding this matter will be greatly appreciated.
