How to convert video signal to sony gvif signal. Is it have a converter to convert this signal.

I am interested in replacing the touchscreen with an RGB, circmventing the GVIF converter (if it exists) and preserving all OEM funtions and content. I want to use the touchscreen to add an interface for an indash PC. I don’t want to add an additional screen for this (as its not very appealing).

Has anyone else looked into this approach? Where do I hack into the touch screen input and the RGB signal to circumvent the GVIF?

There is an NTSC adapter somewhere in the system for the backup camera, which is what the Lockpick 3 ties into. The optional navigation system uses the GVIF interface.

I just got the Lockpick 3 device from coastaletech.com, and used it to feed NTSC composite video into the multi-function display on my 2007 Prius. I am using this to display the video output of my Icom IC-7000 amateur radio transceiver.

The video part of the wire harness DOES NOT appear to plug into the Coastal device. It plugs into the back of the multi-function display. All the Coastal device does, apparently, is enable the multi-function display to read its video input. The Coastal device masquerades as an AVC-Lan-connected DVD player.

So, either the Prius does not use a GVIF digital video format, or the display comes with its own NTSC converter.

The only digital video adapter sold for the Prius, by Cardemand and others, is a scan converter. I am convinced that it outputs NTSC composite.

GVIF is so new that it seems rather unlikely that it would have been used that way. There aren't enough pixels on the Prius display to make it necessary, and I don't think anyone is using it for DRM yet.

So… Why not replace the screen with another one? The converter box costs somewhere around $500 bucks. I’m sure you could get a touchscreen for that price that already has SVGA inputs on it.

Of course GVIF has all the drm protection crap, it’s piloted by Sony…

I’d really like to know what the screen unit the guy used at that spasalon link. He’s sparse on details. Anyone recognize it?
