If you want to use the stereo with the engine switched off then you need to wire the switched ignition in to a feed from position one on the ignition barrel. Easiest way to do this is to remove the stereo first then remove top and bottom steering column cowlings. First undo single central torx screw under column, then turn the steering wheel 90degrees left and right to find the two screws holding the two halves together. Once all screws have been removed the top cover can be lifted and manoeuvred out the way. The bottom cover will need the black ring around the ignition barrel removing, this ring simply pulls out. The bottom cover can now be dropped off the column. The multiplug connected to the barrel can be disconnected by clicked the lock plate in and wiggling the plug free. The position one switched feed is the second wire in, it is YELLOW WITH A BROWN STRIPE. I will not be held responsible if you cut the wrong wire so please check for 12volts with your multimeter first! With the key out of the ignition, cut the wire approximately 2inches back from the plug and strip about half an inch back (fold this in half to give a thicker wire). Crimp on a BLUE inline connector to the plug end. Next strip back half an inch of outer on the loom side wire, fold this over also. Now you need to cut a length of wire to use as your new switched feed, at least 1.2metres will be needed as you can't add wire on too easily behind the dashboard! Strip one end of the wire and fold to thicken if necessary. Now fit both the new feed an the stripped loow wire into the other end of the BLUE crimp connector. Use some insulation and wrap the new connection to ensure no bare wire can touch the bodywork, if it does you'll blow a fuse or worse! Now plug the ignition plug back in to the barrel and with your multimeter test you have a 12volt feed on your newly fitted wire. You now need to feed your new wire through the gap in the dashboard (under the instrument panel) and come out through the hole where you removed the stereo from. Now cable tie the new wire onto the original loom to stop it from rattling and getting caught on and moving parts. Now simply refit the steering column covers in reverse of removal. Your new position one switched ignition feed is ready to be crimped onto the corresponding wire on your stereo wiring adaptor.

Hope this is useful :)

thank you this was very useful I didn't like having to have the ignition on to listen to the radio,
