Anyone know why you need the data interface thing to install an aftermarket radio? Why cant you just install the radio with a harness? I have no clue what the interface does or why it is needed. All I know is it costs a lot.
I recently purchased a new stereo for my 2010 unlimited sport. My local audio man got the wrong connection and said he can't get another. What I am needing is the harness that plugs into the factory connection then you splice those ends to the new stereo connection. Any ideas where I can get one?
