If you are still using your XV6800, and Windows 7 (64 bit), DO NOT go to the Verizon wireless website. Verizon wants you to buy a new phone, so helping you with an old phone is not in their best interest. Click on the link below

Answer the following questions on the website:
1. What operating system are you using? (Windows 7)

You should see this file pop up. VZAccess Manager v7.3.2 (2506b) for your Verizon Wireless XV6700, XV6800, XV6900, XV6950, S Download and install.
Once installed, Windows Mobile Device Center (WMDC) will work with your XV6800 phone running WM 6.1. I can use every aspect of WMDC with my old XV6800. The sync works flawlessly, all of my contacts, appointments, tasks, and media are able to sync with my PC running Windows 7 (64 bit)
