H2 Nav/DVD with CD player?

[aggiehummer...er]

Howdy folks,

I have a potential client who would like to be able to play CD's while using the DVD/Nav system. Aside from buying an entire aftermarket unit, is there a way to add a 6-disc changer to an auxilary input or something like that? This is enough of an issue to prevent him from buying the H2, so I'm looking for a quick answer! Thanks!
