Where would I find the key code to my CDR23

[BeachBum]

Hi Everybody,
I recently switched out my CDR 23 for a navigation unit and am selling the cdr23 on ebay. In the course of selling it, I have been asked if I have the key code card. What is this and how do I find it? Is it on the unit itself?

Thanks,

From what I understand, you don't need a code for the CDR23 like the previous model Head Unit due to it being part of the MOST bus. You will however need to get the head unit enabled on the MOST bus by Porsche.

That's what I understand from reading various bits about it.

If it is the original radio the car should recognize it. Otherwise PIWIS or PST-2 needs to program it.

No code required. Only the previous model CDR22 required the code.
