Yes im afraid your wheel has to come off. But dont worry its a real easy job. Just remove your steering whell - 1 nut in the centre and pull hard and wiggle (the wheel that is) Then you need to remove 3 or 4 black screws from the plate you can now see. Once there out you can remove the plate and also the stalks. Unplug and wiggle them to get it off. Then as the haynes says re fitting is a reversal of removal. 20 mins max to do, even if your a total nonse!
