i've done a search and i've seen the question come up a few times but no answers...anyways, is it possible to put a double or single din unit into the navi cubby? i'm not sure there is even enough room behind there but it would be nice to have a double din navi system up there like the Eclipse AVN5495, in better eyesight than down where the HU goes

 

you can't put avn behind in the stock nav location. many people tried/argued and answer was impossible.

 

+1 here. Not enough mounting space or depth clearence for that matter. Sorry man, no can do. Just wouldn't be worth it.
