Hi my name is Chadwick , you can call me Chad. I just bought a 1998 Jaguar XK8 Convertible. What I need help with is I want to keep the functionality of the steering wheel buttons. I would like to install a Bluetooth module into the armrest yes I do believe I have the phone stuff in my arm rest. Yes I have cd changer and everything works great. An attaching pictures as what I found in my arm rest and yes I checked behind the back seat and no I did not find any modules.
