I mean like a regular head unit that has a video display output. It'd be kinda like a in dash lcd, but without the lcd attached.

Its hard to describe (obviously ) But I was thinking, have the screen mounted in my dash, like a regular tv, always on. Then the hea dunit mounted somewhere else, glove box or center console. But with the video out, you could see the status of the head unit on the screen. LIke the screen in an all in one, but not attached. I dont want to chop apart an in dash for this, cause if It doesnt work, Im fucked.
