What saint said, but if it is an 02 car then some body has gone to a lot of trouble to up grade it @Fran McauleyThe reason we keep banging on about your vehicle is so we give you the right advice.....
You said 2002...but you have touchscreen which came in for the 2006MY (some 2005 reg cars will have too as they made the switch over, particularly 55plate) and so would not be a 2002.
Without correct vehicle information any advice could be wrong.
Stick with it we ask because we strangely care!
