Interfacing With The Original Touch Screen

[Paul v.]

I was wondering, since there are no more then 10 manufacturers of touch-screen matrixes and it would be reasonably easy to source USB/PS2 boards for them, would it be possible to connect to the lexus touch-screen? – if, for example, the lexus touch-screen connects to the motherboard of the head unit via a ribbon cable, then it would be difficult to cut it without doing permanent damage. If it connects via some sort of TTL signalling, it will be just the matter of connecting a few cables, and ipso presto, no need for silly remote controls to control your PC…

Theoretically it would be possible to have both the lexus system and the computer connected at the same time without interfering with each other.

- Did anyone try this?

- Did you remove your head-unit and know what it looks like on the inside?

Any leads are appreciated!

That would be a nice idea, I doubt it could be done using the stock equipment though, I would think you would end up controlling stuff in the car even though you can see the PC image on the screen. maybe you could switch it on and off?

you can buy touch screen overlays for lots of different screen sizes. but I doubt the Lexus Screen would be of good enough resolution to support a PC :(

Resolution is not a problem – I am not going to do 3D drawing on my car computer, - mostly playing MP3s perhaps DVD player and/or TV tuner.

I will see how it goes.

800x600 with large fonts would be perfectly usable on my LS400 screen. – a touch-screen will make it perfect :-)
