Disabling phone speed over ride

I hope I went far enough down the posts, so, if i'm waking up an old thread, I apologize. I have the standard radio on my 2012 and was wondering if anyone has come up with a way to over ride the telephone function cancelling the screen when the car is in motion. I know why it's there but I would like to know. And, why does it let you fiddle with the radio stations but not the phone.
