I own 2002 sc430 and i am trying find the code to allow me to navigate while i am driving?

 

Do a search on this forum.

There are many posts regarding the override codes.

 

Nav Diagnostic override mode Option 1.

Go to the DVD screen (Menu/DVD) and touch the following 3 corners of the screen in this order:
Top Left, Bottom Left, Top Left, Bottom Left, Bottom Right.

This bring up a diagnostic menu screen.

Touch and hold "Override" for about 3 seconds until the square changes color.

Then go "Back."

You can now access all NAV menu items while the car is moving.

Note three things: 1. This setting is lost when you stop the engine, and the setting can only be made while the car is stopped. 2. Don't mess with anything else in that menu -- you can screw up the settings and calibration of the GPS if you are not careful. 3. Messing around with the menus while driving CAN really be distracting and is dangerous (which is why you can't do it --- this override is for testing and diagnostic purposes) -- only use this if you have a passenger who might want to make some settings. In the several years I have known about this, I have seldom found it as helpful as I thought I might. It's nice to know it's there, but frankly, it's not all that big a deal.

Did you mean the headlight switch? If so, which of the 3 positions (parking lights, headlights, auto headlights)?

Interesting 2nd method. Does it work on ALL SC430s? Because there're 3 different 'tapping corner' methods for different years. Thanks.
