all coupes had that option ticked, my car came with it as well (have it in my garage as it took up some room as it hung below the parcel shelf on the drivers side)

should be a harness in your boot somewhere

it was a kenwood branded item and a shite idea as it's in the trunk, most remove them as who wants to change cds when it's raining, lol

got both the stock radio and cd changer wrapped upin as new condition in case someone ever wanted them lol
