CD Player not working in my Vauxhall Zafira 07 Reg?

My husband recently left the lights on overnight on our Zafira, running the battery out. We recharged the battery with a power pack, but it must have caused a power serge, blowing the fuse for the CD player. We've read the manual to see if its easy to change but cant make head nor tail of it. Has this happened to anyone else?? And do you know how to sort it out or should we take the car to a Vauxhall garage - it is still under warranty.|||Once again not quite enough information. Did you enter radio code to enable radio operation again? Is radio working and just no C.D.?? Is it factory radio?? I really doubt there was a surge directly towards or effecting the C.D. fuse and popping it.. You would have more problems.. So does radio work?? Did you enter code, what model radio??|||You didn't say what model year the Vauxhall is... sounds like a dealer thing to me.
