I am wondering if anyone has shared experience in hooking up something like a raspberry pi or a small device to use the nav screen as the display. Or how to hook up a backup camera that could shed some knowledge? Looking into doing something like this since I just bought my TL. Anything would be appreciated!

 

There is a bunch of threads with people have done swaps and Navtool hook ups, it all depends on how good of a DYI guy you are and how much work you want to put in.

 

Used the factory navi screen for a carputer for quite a bit, just used TVandNav2GO for the video input and USASPEC for audio.
