Don't know if someone posted this before, but,
Found something in an arabic forum, worked on my 2007 IS300.



1- Press the INFO button
2- Maintenance
3- Press the DISPLAY Button


4- Press those buttons up,down,up,down,up,down,up,down...etc
5- you will see the hidden menu, press menu for other options (something like that)

I don't think you can change anything though.

 

Up, Up, Down, Down, Left, Right, Left, Right, B, A

 

select A B right left down down up up

Up Up Down Down Left Right A B A

man, I miss Mortal Kombat III

 

, Select, Start

 

I believe there was another way to access that menu with the light switch and some other buttons . It was posted somewhere here before I believe .

 

2 player foo... contra memories.

 

hold any of the navi buttons and then flicker your lights on and off.

 

I wonder if this screen will complete a "FATALITY bonus"

 

no, those are cheats like

Fast mode

enable Smoke, Shao Khan ...etc

Fatalities by using one button

disable blood

and many other options

 

Go to menu, then audio, on the left of the screen press Top Corner, Lower Corner, Top Corner, Lower Corner, and the Diagnosis menu will pop up.

IS350 2006

 

I think that works only on 2006, as I remember.

 

Right. The quick way to the menu you showed is to either:

1. Hold the display button down and click the parking lights on and off repeatedly. The Service Menu will come up.

2. Press display. Tap upper left, lower left repeatedly until the Service Menu pops up.

To exit the service menu, hold Display down and click the parking lights on and off again - this will reboot the nav system, and you can do this while driving.

There are other hidden service menus. I leave it to the student to find these...

 

Audio, Sound, Turn up bass to max, OK, push in cigarette lighter, open/close the cupholder lid 3x, and put on seat belt. This is the code to transform your ISX50 into an IS-F.

 

hahaha LOL ! great one

 

hey, it doesn't work with me, I guess it's because there is no IS-F in middle east, damn.
