Switched live for radio not becoming live...
 

Hi there,

I've got a '99 Audi A6 Avant.. I have taken out the out Audi concert radio to put in an alpine head unit however have noticed that the switched live that should become live when the ignition is turned on isnt working.

The constant live is working fine and every other part of the car works (apart from the dash LCD screen being a bit flakey). I've checked fuse 5 and 37 (which would cover the switched + permanent feeds and no problem..

Is this a fault of the wiring loom or a relay problem? Suggestions please!

Cheers,
Bill.
