Hi guys, im new here, just got a 05 gx470 with 340k km, it has factory touchscreen with rear camera, however i would like some better head unit to replace the old cassette unit, i wonder if anyone has done replace the old one with newer one without remove the factory touchscreen, if so, can i have some advice for which head unit is better, and how to wire it in? Thanks!

 

This module would allow you to do what you're asking about. I haven't used it so I can't say how it works.

If it was me, I'd be looking for a single DIN flip out touch screen that had Carplay capability, my only concern is the angles of the dash, the single DIN slot is set in a bit form the NAV display above it which may not allow you to tilt the display back at all, or even perfectly vertical, and it would block the buttons and possibly the lower portion of the NAV screen.

Something like this:

I replaced my head unit with an Alpine ILX
. But keep in mind I have the non nav vehicle. It's a different job with an ML system. Best to talk to local shop about your options to ensure you maintain all functionality of your system.
