Warning light on console beside CD player.
 

My CD-player and radio have recently stopped functioning and a warning light on the console to the right of the CD-player has lit up (see pic).
Does anyone know what this is supposed to indicate?
No mention of it in the user manual....

OK, I have followed some of the advice given and traced this back an electrical/wiring issue. First of all the fuse for the radio was blown and it keeps blowing everytime I replace the fuse.
Someone mentioned that condensation from the A/C might have caused a wiring fault so it seems that I need to get in behind the radio to check the wiring in hope of finding the fault.
As this is a process of illimination I am open to any advice or tips that people have on how to solve this issue, what to look out for when removing the facia around the radio etc...
