I have followed the threads here about options for getting android auto and apple carplay. I'm also interested in getting a touch screen in my RX. I found this one: https://www.dvdgpsnav.com/blog/lexus...oid-head-unit/

Does anyone have any reviews about this unit? Any issues? Does navigation with 3rd party maps work with the HUD? Does the HUD work with any 3rd party apps? How's the screen quality?

Would replacing the head unit void my warranty?
