I would really want and pay $50 for an app that would allow Iphone display mirroring over the video out cable.

the reason is I would like to integrate my iphone more into my car.

and use an external LCD, or windshield projector, or even the M920 video eyewear to navigate the iphone in a heads up display mode.

as I understand it, only videos them self can go out thru the cable and you still have to look at the iphone screen to navigate.

is this even remotely possible to do ?.
