M4 blue connecte
Here is few pics of back of 2001 Rx with nav multi display screen and radio. First pic of radio (different than 2000 rx w/o nav) with harness: 1.R6 (20 pins) for Radio/cassette assembly (connected with battery, illumination, TX+, TX-, Mute, ACC ANT etc.), 2. R7 ( 12 pins) Radio/cassette assembly (connected with TX+, TX-,Eject). These pin connections already we have our non nav radio harness R2, R3, R4, I just have to match with the designated pins and wires.I added pdf radio digrams for both RX's. Second pic you will see 3 connections. Those are:1. M5 (8 pins red arrows) blue for mostly power, ground acc etc. 2. empty white for video input (like Ipod, Iphone etc.), 3. M4 (red line) blue connected with the nav ECU N4 for video input. 4.M3 white (14 pins) for radio, instrument panel connection, speed sensor, parking brake, etc. I will post all the updates.

I am really interested in trying my hand at upgrading my 03 Rx300 audio system to a newer one with navigation. I am brand new to Lexus as we just bought this vehicle a few weeks ago and have about 600 miles on it so far. I spent many years in electronics troubleshooting and repair in the Navy, so I am not afraid to solder, splice, etc. What is the latest (newest) radio system I can install in the factory bezel and what is the newest nav system (computer I have seen some say) that is compatible with that audio system? I also want to have bluetooth and aux in for ipod/smartphone.

Please look up the thread on AUX-in. If nothing else it will give you insight into compatibility issues. There is at least one person who did an retrofit [which also included and upgrade ... Lexus has gone through multiple generations of updates '99 is now 20yrs old).

I know this is an old thread but I have a good angle to acquire a complete OEM navigation unit from a 2001 model. My model is a 2000 non-navigation of course. After reading through this thread wanted to be sure before I dive in on what’s required?
-Head unit from center console, complete with harness
-DVD/ECM unit and attaching harness from right trunk area
-GPS antenna connecting harness running along back trunk area
-Splices to harness as shown in diagram, if custom harness isn’t available
Any input would be great!
