Allows me to synchronize my contact with Outlook & use my phone as a modem. I can transfer pictures and ringtones from my computer to my phone and from my phone to my computer. It even works with my wife's Verizon V3m, some tinkering was required to get the multimedia features to work on the Verizon phone (instructions were supplied my the vendor), but at the end everything works great!! As an added benefit if I get a new phone I don't have to worry because this kit works with almost all Motorola phones.
