I don't really want to spend the $250 on the AV electronics box just to find out the stock screen is so crappy that I can't do much with it.

I searched with limited results as most of these applications seemed to be centered around installing their own screens.

also, is there a ways to just install a switch or something to switch between navi signal and an alternative signal?

if u have any input, that would be super duper.
