Hey all!

So, unhooked the battery in my 2003 C4 to clean stuff up. When I hooked it all back up, I got the usual "PSM failure" and "ABS" lights and such. Fired it up and drove a bit and all is fine.

However, the radio doesnt work anymore! I searched here and found out about the 10amp fuse on the back of the unit. Took it out, and replace it (even though it wasn't blown).

Turn key to on and nothing. Changed the 2 fuses in the fuse box (also not blown). Tried again.

THIS TIME the "Porsche Start Screen" popped up, but then black screen.

I even disconnected the amp in the frunk, and nada.

I can hear the CD's moving around. But can't play anything. Tried pushing CD and then FM. Tried turning key off, locking doors, turn on, etc...

Hate to replace this thing with aftermarket. Is there "anything else" to try??

We are here in Parker Colorado if anyone has thoughts!

Thanks!
Bill

 

dumb question but did you put in the radio code?

 

Nothing pops up to let me do anything. The "Porsche" screen lights up, and then nothing... None of the buttons work.

 

Here is what the stereo looks like (has the BOSE system too).

 

I was wondering if I could get a radio code here? Serial no. 25006445
Type 4362 thank you so much!

 

Ended up buying a replacement from an 07 911. All good now!
