I am very very grateful to one of the very first posts who illustrated the process, many years past.
For the benefit of new comers, here is the link: the pdf is downloadable from

You only need this part.
The matching Manual, CRT1899, is useless. It has wiring diagram for the radio, but this is a Pioneer manual. It does not explain how to remove the unit from the Lexus dashboard. For that, you need to print the pdf above.
Plan 2 hours for the compltet procedure if this is your fist time.
What took most time is removing the vent, trying not to apply excess force. Eventually it comes loose. Bur don't rush it.
You need a flat blade, not too thick (1/32in), about 1/2 in wide and about 5 in long. Yoiu can taper it at the end with a file, for easier insertion.
If metal, I higly recommend putting making tape over it so as not to scratch the dashboard/bezel. ( I used 2-3 layers). It worked great.
Similarly, I highly recommend masking tape along the sides were you insert the blade to free the vent insert.
Not required, but I recommend strongly color-coding the connectors and receptacles with matching stick-ons, before disconnecting the unit form the Dashborad.
What you remove is the DIN Chassis with carries both the Radio unite (2DIN high) and the climate controller(1 DIN high) .
You need to take the radio unit out of the DIN Chassis (4 golden screws on each side)
to take the radio bezel off. There is a bezel catch in the space between the radio and the climate controller and you can't reach it unless you get the radio out of the DIN chassis.
Once the radio is out, it is obvious how to swap out the display assembly. Takes a couple of minutes.
Reverse assembly and re-installation takes less than 10 minutes.
Still, don't rush it. You don't want to loose screws or scratch you newly restored unit.
If you do it methodically, it's not very hard to swap out the LCD. Saves $$ and will make you proud.
