2006 Navigation Secret Menus

Does anyone know how to access the secret menus on a 2006 Mazda Navigation system? (I have a 2006 Mazdaspeed6)

Do the secret menus allow you to input POI's while driving?
 
I was playing aruond with my phone the other day and thought that there might be more codes that go to different menus like the #0setup* so after 2 min of playing i found one..... type in #help* and you will go to a menu that has phone info and an interesting option to add a new line. Not positive that this is new but thought i might as well post it. Also has info about BREW version etc if that helps you programmer.

Thanks.
 
There's only one I know of:

If you hold and press voice for a few seconds, another menu comes up that allows you to adjust contrast and brightness.
