All fixes if they do not include a switch will prevent the navigation unit from receiving the speed data, so the navigation will think that you are not moving and will allow you to enter data. However, because the navigation unit is not receiving that speed data, it must solely rely on the gps satellites for your current location, and since there is a delay in getting that data (long distance to the satellite), the nav will not update properly until you have stopped using the hack and then wait a minute or two for the nav to get the speed data again.
Thank you so much. It would have been nice if they linked the airbag sensor to the Nav so if a passenger was detected you could use it in motion. I do like to browse for restaurants particularly with hungry kids in the car and that is what I miss most about the lock out. I will try the voice address function.
Thank you to everyone.
