Where my CCC folks at? I've got an Xcarlink multimedia video interface for sale. This unit has picture in picture enabled ($100 addon). Unit plugs into the back of your existing head unit and adds the ability to use a reverse camera in a pretty much OEM way. Automatically switches to the camera mode when in reverse. All you need to add is any boot handle reverse camera from ebay. You can also connect any other video source to the module if you'd like (DVD, VHS, etc.) and it can play it through your idrive.
