Piece of cake. The tuff part is getting the bulbs. Volvo does not list the bulbs for the radio in their parts catalog, but they are the same bulbs that are used in the doorlock/window switches which are in the catalog. So ask the parts guy for the light bulbs for doorlock/pw swich. Take the radio out, there are several secrews holdig the face plate on the radio, remove the face plate then there are some tabs and I think one screw that holds a Printed circuit board which is just behind the face plate. Gently bend the tabs so that they do noy engague the printed circuit board and remove the printed circuit board. The bulbs take about a 1/4 twist to remove. They also have a rubberish filter over the bulb, place that on your new bulb and install.
