Hi Kerry,
I'm looking to update the infotainment system on my 2012 GS450h and checked out the Tesla style unit, but I have found what I think is a better one, the T'Eyes CC3. Unfortunately the wiring harness won't fit mine, but it might fit yours, if you have the tape unit at the bottom.
I asked T'Eyes how I could make it connect to mine and they say it would be a custom install with different wiring, but the unit would fit the dash.
If anyone knows of someone who has made this work, please reach out.
Kindest regards
TerryRS
