I have the 2003 Odyssey with the built-in GPS. I was wondering if
there was a way to get a DVD player (or upgrade to the existing system)
that would allow it to play DVDs through the dash and through an
overhead screen in the back.

Right now, I do not have the overhead on the roof and I'm sure I could
buy a new system, but it sure would be nice to use the in-dash screen
and possibly the touch screen.

Thanks!
Tom
