I would like to 'hardwire' my satnav and 'dash cam' in my X3.

What is your question?

The problem is that the fuse 'card' supplied with the vehicle shows that several fuses are allocated for one item. For instance, the radio/disc player has 11 fuses allocated. As my cigarette lighter is on permanently, I am trying to find out which fuse I can use (with a piggy-back fuse) which only supplies power to an item when the ignition is switched on. Obviously, I want to connect to a fuse in the fuse board behind the glove box rather than the one in the back of the car. Can anyone suggest a single fuse number I can use. Thanks, in anticipation.
