1: you have to pop off airbag, remove steering wheel, undo securing bolt, unclip unit, remove all wiring plugs and swap over radio stalk to new unit. and fit new unit. wiper and indicator and airbag switch all one unit.
2: not sure if there are external bulbs on display. pop off blank trims either side of display, undo screws underneath trims and remove unit. if there are no bulb units on outside then you will need to replace display.
