Everytime I start my car up, i have to manually agree not to look at the nav while driving - a nuisance. Is there anyway to *hack* the NAV and turn this off?

Similar question with the seatbelt "binging" - can this be turned off? My laptop bag full of books on the seat next to me will set it off. I always wear a seatbelt when i drive, so its not a safety issues, just a nuisance.

Thanks!
