you will need to pull out the headunit and unplug the antenna connector.. this is the big black tube at the back of your headunit.. but wait, some cars use an extension cable which can make installation easier, and you are lucky enough that your car also have a sub antenna connector..
So what u need to do is undo the 2 mounting screws on the antenna base and pull it out.. unplug the cable, plug the new one in and then screw it on... ur done !!!
