Greetings to the Forum:

I am a new member, so please bear with me. I did a search on this forum and could not find any posts about the information I am looking for, so I decided to start a new thread.

I am looking for information on the data buss format and connector pin outs for the touch screen on the GPS equipped 2000 Lexus GS-300. I would like to add a back-up camera and replace the original screen with a newer one that is not so susceptible to cold. I know someone who can write the code, but I need to know the data format and voltages the original screen is expecting. Also, the connector pin-outs and whether or not new connectors can be sourced.

Thanks,
Jim T.
