The RAZR/RAZR MAXX docks work as well. One of the users over at AtrixForums,com has successfully used the RAZR Desk Dock (89527N) with the Atrix HD. It's essentially the same as the one they are selling for the AHD, but it can be found for cheaper (not sure if the insert might be different). I am using the RAZR Dock Station (89526N) with the AHD. in addition to the HDMI and audio ports, it also has 3 USB ports and includes the HDMI cable. The USB ports function perfectly with the AHD.
