Ok i have a 99 xj classic. My buddy works at an audio place so i get all kinds of stuff for free and installed. I got a $1200 remote start hd display and iphone start app all the works windows up n down ect installed and didnt pay for it all free. He is molding a 10" screen in my dash. He said go big or go home. Here's what i wanna know other then dvd's ect i was wondering if there's some kind of software or device i can hook up to it to display like all my ecu readouts. thermostat spark ect all on the screen showing digital display nice tho. ive seen done via pc but dont know software. thanks for any advice
