That looks promising. How does it install? The web site wasn't too clear on whether I have to crack open the LCD display or if it goes back by the DVD unit. How/where did you put the switch?

 

Folks, I've been beating my head on this issue for a few months. Tried to get a VGA signal to the darn screen, but failed after many, many different circuits. I decided to swap out the stock screen with a lilliput, but I still wanted to use the stock navi if possible. I busted out the 'scope and measured what the navi unit was putting out:

SYNC: Composite sync, 15khz horiz, 30hz vert. Seems ~2vpp.
RGB: Looks to be around 0.4vpp

It looks like this is what the screen is looking for, if anyone still cares

High-tech scope captures attached.

 

I have just purchased an OEM Nav screen and trying to figure out how to link any aftermarket DVD players. Can anyone pls assist? do I need AV switcher and how do I do the wiring to back of screen as I do not have the wiring harness. Thanks
