i have an 02 ls430 with a screen. i’m wondering if it’s possible to replace the screen itself with a bluetooth one with apple carplay and wire up the AC and nav to the screen, or would it be better to replace the radio and cd changer and have 2 screens

 

If you don't want to add a second scree, you can get a GROM Vline2, which is what I currently use. The resolution is low, but I have CarPlay and that's all I really wanted.
