    Does any one know how to update nav system on car? I went to Maryland from Ohio and speed limit for road being traveled was off most of the time.

    Not even worth it IMO, just get a Garmin unit with free map and traffic updates for life. I checked what it would be for my '12 because of how convenient it would be, but it was probably around $200 so I got a Garmin for $125, which has more features than the car.
