AJ will probably respond, but the upgrade comes with detailed instructions, including pictures. I had some anxiety about doing this, but it is actually quite straight forward. You remove the pictured screws from the case, lift up the top, remove two screws from the HD, and detach the 50 pin ribbon and slide out the old HD. This is done after connecting the Audya to your pc via USB and backing up your reg's, midi's etc.

All becomes very clear when you look at the instructions. I am just average and it went very well.
