I have a 2003 Porsche 996, and after the battery died, then jump started it, the radio will not work now! No power no sound. Checked the fuse block, and the radio fuse is fine. The fuse next to it was blown, so I replaced it with a new one, but still NO radio. Is there a fuse right behind the radio, or another inline type fuse??
not really sure with porsche radios but it sounds like the radio needs a code to make it work again, try calling a dealer and asking the service department. They should be able to give you a code..
