Not really sure, however, you can see I think.
If you turn off the radio. Press and hold the settings button, turn the volume know anti clockwise about 40 clicks. it should take you to a hidden menu.
From there scroll down to the camera option. I assume if you don't have the cam option then it can't be fitted.
Pm me if you need help.
