Ok, still kinda on topic...
I used to have a Toyota with Nav, and there was a "secret" service menu that was supposed to be accessed only by dealers. Anyway, after touching a few random places on the screen in a certain order, I could manually override the factory navigation setting which would then allow me to input directions (have full control of the navigation software) while driving. I was hoping there was a similar option on or WK2's (I've got the 730N). It was annoying because I had to repeat the step everytime I turned on the car... but I couldn't complain because the fix was FREE. Any ideas?
