Hi Tom,
first You have to "unzip" the files to your PCs harddisk.
This files you can eihter copy via USB-Stick to the Audya or via USB-to-PC-connection.
If you use the USB-to-PC connection :
BE SURE THAT YOU USE THE "DISCONNECT HARDWARE" function of the Win-PC prior unplugging the cable !!!
, otherwise files on your Audya-HD may be corrupted !!!
Even though under Vista / Win7 this ist not necessary for "normal USB-Sticks or USB-HDs" : FOR AUDYA IT IS !!!
BTW: You sould, when using an USB-stick, copy the files form the stick to the Audya´s HD in one of the 10 "User_Styles" subfolders.
