    Hi guys. Dunno if anyone has any ideas, I removed a double din concert unit from my a3 about 4 months ago. I just sold it on but cant get it to turn on. After everything if plugged in it just doesnt do anything! Any ideas??

    Are you testing it in the car or on the bench?
    Is the fuse on the back OK?
    Is the perm live feeding the HU OK?
