Has anyone tried this override for Nav on 2006?

Found this on another website... Does it work (I am thinking someone has tried it already)

I picked up this tip from another site. If your Camry has a NAV system, you can OVERRIDE the programming of your system, thereby allowing you access to certain NOT-normally-available functions while driving.

At least two things are possible by using the OVERRIDE feature: you can manually enter addresses while driving, and you can access normally locked-out features (phone book and manual dialing, for example) of your Bluetooth phone.

Here's a summary. It takes seconds to do, and is simpler than the explanation would lead you to believe.

On the panel to the left of the NAV screen, press MENU and then on the touchscreen, press VOLUME. Then, in the upper left corner of the touchscreen, press the speaker icon once. Then, in the lower left corner of the touchscreen, where NO icon exists (blank), press once. Then repeat the last two steps, pressing the speaker icon and the blank lower left corner again. To summarize, the sequence is:

MENU > VOLUME > VOLUME ICON > BLANK >VOLUME ICON > BLANK

This will bring up a HIDDEN touchscreen. To use the locked-out features of NAV and Bluetooth, touch and hold the OVERRIDE button for five seconds. It will turn blue to indicate you have highlighted it. That's it! However, the OVERRIDE will be discontinued when you power off your car, and you will need to repeat this procedure each time.

NOTE: YOU CAN ACTIVATE OVERRIDE AT ANY TIME WHILE YOU ARE DRIVING. THIS DOES NOT HAVE TO BE ACTIVATED WHILE STOPPED. THEREFORE, YOU CAN LEAVE IT ALONE UNTIL NEEDED.

Obviously, Toyota has locked out some features for safety reasons, but on long trips it may be useful to search for a restaurant while you're driving, or dial a phone number from your saved phonebook. I haven't yet been able to check if CALLER ID is available when OVERRIDE is used, but that would be excellent, too!
