Factory Nav touchscreen as USB or PS/2 pointing device
 

Hi - I've done my homework and am pretty sure I know the answer isn't the one I want, but was wondering if anyone knows of a device that allows you to use the factory navigation (in my case 2003 SC430) touchscreen as a USB or PS/2 pointing device. I'm well aware of RGB converters that let you use the video, but haven't found anything that will let you get at the touchscreen.

Any pointers would be greatly appreciated.

Thanks,

I've been doing research too...and here's the most promising

There is a product called CAN-view that is made for Toyota Prius to allow for extra functions and viewing of data from the Hybrid system. The unit can output touch screen coordinates (through a serial port) from the stock Toyota touch screen (which should be the same as the Lexus one) because it interfaces through the Navigation computer connector.

This person has installed a Mac in his Prius and able to control it via the stock touchscreen using the CAN-view unit. http://www.kusnetz.net/prius/

Check http://www.hybridinterfaces.ca for CAN-view.

The creator of CAN-view says that if the Prius communication system is the same as the Lexus, then it should work...and we can use the touch screen coordinates coming out of the serial port of the CAN-view...I'm almost willing to bet that it should work since the Navigation computer and connectors looks almost exactly the same.

I don't have the money to try this out at the moment...but maybe it's worth your while to check it out if you really want this to work.

Hi,

Have you found a solution already?
