Looks impressive but it is not really helping my case :-(.
I would love to know what wires, at the back of radio & display unit are responsible for what. I have to replace both and from what I understand they do not look exactly the same at the back.
For example it would be very useful to know, what wire is responsible for antenna in the rear and what wire is it in new radio. So that I do not have to go through all the options to see if everything is working. Especially that I will not plug in GPS unit (I do not have it), so some wires will have to stay unused. I still hope the rest - display for other than sat-nav functions, climate controls and radio will work without it. I also hope that US and European measurements scale (F & C) are somewhere in this unit not in the main computer of the car....

Lexus like other luxury lines, uses proprietary standards for entertainment. Audio signals between units are analog, but are dual differential and the level is higher that what is referred in the industry as line (preamp) level. If you want to do mix and match good luck to you. Communication between the units is through Lexus's serial protocol.
There is enough discussion on line in (search for these).

I honestly don't have a clue what you just said and how it refers to me 😞. I don't want to mix and match anything, I simply want to change/replace radio and display.

I tend to ramble, so if it does not apply to you, please ignore. Stay within Lexus line. Also there are 3 manufacturers of audio products.

gazi001 - YOU ARE A HERO!!!!
Last question :-)
I understand you do not have a similar info for units with navi?
Still, having info as above is a GREAT HELP!
From what I understand I need to find corresponding wires on new unit to make sure "old" wires will be connected to their exact equivalent in new unit.
Last question - does any of you actually have radio with sat nav as the one I have just bought?

OK, I am about to make a swap.
I got all the documents I was able to find on forums however I am missing description of two sockets/plugs:
1. multidisplay - I would need to have schematics of this plug, so I can correctly connect the wires
2. instrument control panel - as above, so that I know what wires from existing set (old radio without sat/nav) go to where in new unit.
I bought "new" unit second hand so it did not came with any wiring :-(
Can you help?
