Alpine 6-Disc DVD Player (Help finding a part)

I cant seem to find a replacement 6 disc magazine for my 08 Rovers rear seat entertainment. I don't need the whole alpine unit, just the magazine that holds the 6 discs. The AD is slightly clueless, and ebay searches are frustrating. "alpine and DVD" searches don't return the part as listed on Roverparts and Roverconnection; only a cd magazine for older models.
