What is the number one thing to change in the inside of your RX300? For me, it was the information blue screen, which did nothing for me. The thing I wanted in my car, never came with, which was a Navigation System. I always wanted to have it, but never liked the ones you put on the windshields, I figured to I was going to wait and my next car definitely would have it. Then saw this post and it changed my mind and had to have it now. https://www.clublexus.com/forums/sho...d.php?t=307408 By Flash14 who bought an OEM Navigation KIT and installed it him self. I thought to my self wow!!! I want to do this mod as well. So I did. This OEM Navigation cost me $1500.00 for a GEN3, if you want a GEN4 upgrade it would be a little more, you can see the differences between both with the pictures I have provided. took about a week to get to my house and 2 ½ hours to get it up and running. The installation was the easiest thing I have ever done. Everything came with pictures of previous installs and instructions, basically a plug and play installation. This is a complete kit, with all the cannon plugs, and only needs a couple of wires to be "tapped" into, one for speed, diagnostic, reverse (optional) for back up camera and the power antenna. Like I said every step is covered with pictures on where these wire taps goes to. You can not mess it up, that’s how easy this is. You don’t need experience to do this just 2-3 hours of your time. It is the exact stuff that Lexus originally put in, hooks up to the existing wire harness. I have a newer computer than the ones that originally comes with the 2001 RX300, mine is a generation 3. Navigation system is better than expected, voice turn by turn; the display is touch screen and is interactive with the radio, CD player, sound adjustments, fuel economy/computer, maintenance scheduling and reminders.

Pictures of the before, some installation pictures and an after shot of it done, just amazing…

 

This is what the unit looks like when it arrives to you...

 

Behind the unit, you can see all the wires are labeled so you know what they are and you don't have to guess.

 

This is the GPS DVD Computer which will go in the trunk.

 

This is where the GPS DVD Computer will be so its out of the way.

 

This GPS tells you Voice turn by turn and and audio prompts, so you will hook it up to the amp in the back of the rear seat to let you hear the voices through your speaker w/o interrupting your music. Here is the amplifier.

 

You will need to remove your glove box to work under neath with plenty of room. Here is a picture of it removed.

 

I will now show you the 3 places where you will need to tap the wires to...
Picture ONE this is the speed sensor wire tap.

 

Picture TWO, this is the power antenna, which allows your antenna to go up just like it always have. It is located behind the radio.

 

Picture THREE, is the wire tap for the diagnostic connector. It is located on the drivers side by your knees.

 

And the finished product.

 

I will now post pictures of the screen, and some of the functions.
