Can anyone tell me how or where I can go to have my camera display switched? I have a 2015 3500 and when I ordered it I ordered the cargo camera (big mistake, useless) not knowing this moved the backup camera to the rear view mirror and the cargo camera to the radio. With the backup camera in the rear view mirror it cuts the mirror image in half and it is sometimes very hard to see the camera image in bright sunlight and reflections from the mirror, basically sucks. I understand in 2017 they reversed this and now the backup camera is viewed in the radio and the cargo camera is in the rear view mirror. Can this be done on my 2015? Better yet, if both could be viewed in the radio by selecting which camera you want to view this would be awesome. It is highly unlikely anyone would need to have both cameras on at the same time anyway. I would very much appreciate any help you guys can provide.
