getting ready to buy 04 MT TL so I've been researching the whole carputer idea for this car. I want to get the non-navi TL and put a 7" or 8" touchscreen in place of the stock screen. I don't want to relocate the stock screen, I want to replace it.
How could I get this system info (AC and stereo) to display on my aftermarket touchscreen? see pic from TLer
I wouldn't be opposed to having a switch that would let me change inputs (one input would be the stock system and the other would be my carputer)
