My father-in-law just bought a new Prius and the nav system had some new roads and locations on ir from my version. My son thought he would try it in my Avalon.

I assume its the standard dbl DIN size. and yes it is used by the audio as well. That part works fine. its just the DVD nav player that doesn't work. The display tells me the that the disk is unreadible. Both the Prius disk and my old stock disk.
