Thanks Leo, not sure how old, I've had the car 12 months now. The battery died a few weeks ago, according to the AA mechanic, the battery died due to me leaving the car unlocked for about a week. I'm a trusting / absent minded soul. I,be just jump started it again, and noticed the DVD unit in the boot and the unit immediately underneath it is wuring away when everything is off. I may try disconnecting the battery.
