I finally caved in and will be installing a double din on my 2001 lx470 with mark levinson non-nav.
I choose the one below its pioneers 2019 flagship model for a great price, paid 480 shipped to me at abt.com
What i really wanted was android auto, and with this unit you even get wireless android auto which no new car currently supports so upgrading 2001 tech to maybe 2021 when possibly wireless android auto/car play makes its way into new cars since car companies are just now barely adopting wired android auto/carPlay.
That's a good price. I think you'll be happy with with it. I've had mine installed for a few weeks now and it's a very nice upgrade. It's dark here but I tried to get a picture.
