    a6 avant symphony with bose (no sound )

    I have an a6 2.5tdi avant with symphony and bose .
    The problem i am having is that the display on the head unit does not light up (but shows the radio in the dashboard binnacle )
    and also there is no sound from the speakers from the cd/tape or radio.
    Also it does not display safe so i can put the code in ?????
    I have checked all fuses and they are fine!

    There are 2 fuses, one in the fusebox (Radio) and one on the back of the HU. Chances are the HU fuse has blown
    Is this the original HU or a replacement?
    If it's original it won't need the security code as it's coded to the car.

    I have checked both uses and they are ok!

    Was it working before or has something happened to cause the fault?

    its always worked but i had water ingress into the cabi.

    Took the head unit out yesterday and took it to a pal who deals with car audio .
    He has just phoned to tell me that the unit is dead due to water ingress (something has got the boards wet )
    OOOPPPPs !
    RIP head unit
