I just purchased a 2009 xlr-v and would like to have a backup camera that is not wireless. I have been told by one professional that it cannot be done in my navigation screen due to the type of radio that it has. He also stated that he would have to completely change the rear view mirror and locate it in a different place due to the type of mount currently present. This would leave marks where the mirror currently is located, and changing the mirror location would affect visibility. Has anyone else had a backup camera installed successfully?
