Hello,
First, I would like to say I have a 2007 Rx350. While I was messing around with my nav I found another hidden screen. While pushing the info button turn lights on off 3 times. This will take you to the Diagnosis menu.

Then press on the upper right corner, upper left, bottom right, bottom left of the screen. A NEW SCREEN WILL POP UP. (Product Diagnosis Menu) The menu contains

1. Drive Recorder
2. Touch SW Adj
3. Calibration
4. Vehicle Signal
5. Soft Version
6. Tel Voice
7. TFT Adj
8. Display Memory
9. SRam Clear
10. BT RF Test
11. Rom/Ram R/W
12. Check Sum
13. Data Logging

Hope this helps someone.IT people get to work and find us something we can change.

 

I've heard that if you tap out a complete verse of "Jingle Bells" on the car horn beginning precisely as the 350's clock hits midnight, a picture of Santa Claus will pop up on the nav screen.

 

I tried that and the HOOTER Girls showed up on the screen..

 

wow i love the hooters. will try it out today

 

It's the new cooperation between Lexus and Nintendo.
up, up, double left, left, down, left, down..
ultimate combo

edit: i'm not doubting the OP.. just the idea is funny that's all.

 

Just thought I would post to support Spotnsabby....

I just tried this combination on my RX350 and it works just like he said in the

instructions....

Thanks for the info Spotnsabby

 

Tha's nice, but what can we do with it?

 

Hey, I wonder if this is where the customizations are performed. Too bad we don't have any Lexus technicians in this forum.

 

It says diagnosis, so I imagine it merely allows access to the things recorded by the computer.
