Maybe, i may have to get the garage to look at it, thank u anyway
If you want a cheaper option, you could try getting some radio removal keys from eBay. They're probably only a fiver or less, and they're always good to have anyway. Take the radio out (make sure you know the radio code!) and have a look at the aux cable, to see if it's still in place and in good condition. A garage may charge a lot and not even solve the problem.
Does it switch to CD etc, because if not and it's stuck on FM radio, then the FM/AM button may be stuck on, as if it's always being pressed, in which case some compressed air blown onto the button may be able to loosen it up.
Hope this helps, and you get your problem sorted! .
