my daughter broke the touch screen on her 2013 dodge journey. she can get a used screen for about 100 bucks. it is the 4.3 inch screen. when i replace this for her will this require a trip to the dealer for a reprogram or can this just be changed out? thanks

It should not require reprogramming. The radio will not know that the screen changed. If the radio does not know, the CAN bus doesn't know either.
