They don't have any units for non-navs from what I can tell in their configurator, I've spoken directly to them as well and told them about the swap, didn't seem like an issue, granted I can get the head unit to work.
The issue is - can a Non-nav car supply power and get the display functional without additional wiring harnesses?
All OEM Lexus ISX models use basically the same monitor from 06-13, but what I am not so sure about is if it's just plug and play (since I'm not going to use the factory navigation or mics or anything, just want to see that I have a monitor up and running so I can order the Vline)
