Hi they do work together but i have to turn the rear and front camera on and off from the window switch not the mute button because it will turn on the bluetooth. This is only when you turn the camera on with the window switch not when its in auto mode just put in rev and the camera comes on. I use the mute or talking mouth button only for the bluestar unit. If you do hit the mute button to cancell the camera you also have to hit the onstar button to cancell the phone, hope this helps
