Range Rover L322 Audio Failure

Hello fella's

Help please! My 04 L 322 has just been in to the garage for a round of expensive jobs ooch... however on return the audio on Sat Nav, Radio, CD and Aux feed has disapeared completley? Before the garage rip off the dash board and present me with another huge bill for replacing the entire unit, could the problem be a fuse or simple loose connection problem in the left hand side boot compartement?

Anyone had a similar prob? Cant drive without my tunes! It's killing me!

Was the audio working ok when it went into the garage?? If so then the garage has to repair it at their expense.
