You could, but thats he OEM tap in point.

Could i do the same for the 12v just tap into another 12v cable going to the the tuner or radio module? do you know what colour the 12v would be?

I would take the +12v from the rear, as for colour you would need to use a meter to find one.

Would my 2001 X5 which came with factory fitted navigation have a JUMP that i could test out on my 525i?

No, factory nav has the TV in an incorporated loom.

And whats this Reverse signal?

thanks

For when the car is in reverse, so that the nav "knows" you are going backwards.
