Default Navigation Secret Keypad

Im not sure if this has been discussed here before but theres a secret keypad for the navigation systems on our navi systems.

1-Hit the hard menu button

2-Goto Display settings

3-Hold your finger in the bottom left hand corner (approx 5 seconds)

4-Keypad appears


The only codes I know of are
295660 a diagnostic menu
9448 is a more extensive version of 295660.
660 also works but you have to turn off the ignition and wait several minutes before the radio exits this menu.

DO NOT CLEAR/RESET ANYTHING. I am not responsible for you messing up your radio.

Anyone else have more codes?

I was reading on other sites of one to disable the OK prompt or to make it once every 50 times. The code they were throwing around was 1791 but ours accept 6 digits so who knows.

I think this could be used in place of a lockpick for just the dvd in drive functionality. Maybe even to access some new customizations?

If you want to see more pictures of the menus themselves....http://s274.photobucket.com/albums/j...0PIN%20SCREEN/

just went out and tried it. 9448 does not work, when you it ok it just goes back to the nav screen, 295660 has the most options. 660 has less options but different options than 295660 like microphone and button testing.

do any of these codes allow you to deactivate any of the "in motion" limitations? What are items do they allow you to change?

the 9448 code works on mine....ill take some pics and post what shows up in different screens...the only thing is that none of these have options to turn on/off only diagnostics (like microphone level or touch screen calibration)

i really doubt there is a dvd in motion code but there could be im more hoping not having to hit the ok button everytime i use the nav or more features etc etc

I was thinking the same thing. There may not be any such code.
If there is, maybe its only works in Denso units made for non-US countries. :confused2: Hopefully its a software bypass added in.

9448 didnt work for me. After entering it, it went back to the screen with the hidden button. I'll retry it later. I did notice that once you're on the keypad screen, you can enter codes and move through menu "while in motion".

one othe thing..When playing a DVD, the in-dash(on screen) controls allow you to scroll left or right. This give you different menu options. One of the options is "DVD Setup". Nothing much on the screen. I didnt try touching parts of the screen for hidden buttons. no luck. But I will try again when i have more time.

does anyone here have a newer nav disc than mine...my pn is 15934919 your disc could hold the key to what i need to possibly find some more codes

more specifically...if you care to fight the fight...put your nav disc in your computer and look to see if there is a file named "LOADING.KWI" and then PM me

from what ive read on other forums this is an update file for the software on the radio itself...others that saying 9448 does not work leads me to beleive that your radio is a newer version of the software than mine

My disk is p/n: 25850927

295660 and 660 works

9448 and 1791 does not.

Here is a listing of the files. No LOADING.KWI that I can see
