I don't like creating accounts for websites unless I really have to. Would this allow me to update the speed limit on my residential street? The nav thinks my 25 MPH street is a 55 MPH street, so if I want to set TACC while driving on it, the car floors it to get to 55 MPH unless I crank down the dial quickly.
