I bought a new electric aerial for my girlfriends S40 (she decided to listen to the radio in the car wash) which was supposed to fit the S40 but when I removed the old aerial it had a different number of wires. Also, once the aerial was removed, the stereo and internal lights don't work and the door open light on the dash is permanently illuminated and the light showing a car with a cross through it is also permanently on.
Help.......................
