Help pcm 1 radio unlock code

[gIzzE]

Old post I know, but wonder if anyone can help?

I thought unlock codes were not possible with the PCM1 from the serial? I'm hoping I'm wrong.

I bought the car and the owner said he would get the code from Porsche, however the code is not working.
Remembered he had the PCM1 replaced as he had the dead screen on the original.

The replacement unit is as follows....

BE2580

Serial: 15089049
MLFB 5WK 78015



Now, if I can't get a code, can I simply use the working front panel/screen on the original head unit?


Thanks in advance.
