I dont get it. Why dont you guys use the voice recognition function of your TCH? If you already know the number you can dial by number. If you know the address, you can enter the address via voice recognition. If you just want to browse the locations in the dvd, well, you're better off pulling over and using it that way anyway.

I come from driving a 2003 Acura TL-S and the nav didn't lock anything out, so it can be used while in motion. I do miss that "feature" but I can live without it, especially if you can voice prompt it instead.
