Hi Alan. I had a 03 one in last week and the illumination on the switch only came on when you switched the lights on or if you switched on the ignition,but went off as soon as you turned the switch off (lights or ign ) This car can have it lit day and night with it swiching off or flickering on and off sometimes (seen in the dark)
Any idea what the units in the boot are ? n/s behind cd and o/s above battery
