Right it depends on your head unit TBH but you should have a red live and a yellow live wire (please check colours before doing anything because thay do vary between head units!)

The red will be the main live and on the ignition so cuts off when you switch off.

 It sounds like Your yellow one which connects to the live also is on a switched live prob on the ingnition aswell,

 You need to put it onto a permanent live so it keeps your memory!

HTH

i had a nightmare trying to sort my problem out today as i was messing about with the live wire behind the headunit i touched the back of the headunit with the live it sparked when it touched so now my headunit dont work  :evil: the headunit does not turn on it wont play or the screen wont come on strangely all it will do is eject a cd i checked the fuse in the headunit it looks ok

so have i killed it or is there a fuse i could have blown that i can change

Have no fear,sounds like you blew the fuse on the car. Go to the fusebox(near your right knee) and on the detachable cover is a key that will tell you the fuse to examine.
