I wonder if any double din navi w/ dvd HU can play the DVD/CD while using the navi. I wanna get a double din navi/dvd hu to replace the stock hu and put a LCD screen in the cubby. I wonder if it is possible. Thanks in advance!!

 

I believe the Pioneer AVIC-D2 should fit the bill.
This is from the pioneer website:
Taking advantage of the large, double-DIN size, the AVIC-D2 hides two separate disc slots behind its face panel — one for navigation map DVD-ROM and one for CD (audio CD or MP3/WMA). Music from the CD player or other audio source can be enjoyed while the navigator is in operation — in other words, there is no need to eject the map DVD-ROM.

Hope that helps!!!!
