Radio Code Problem (2000 PCM)

[Andrew]

After a dead battery, my PCM displayed the screen to input the radio code. In the past, I have entered the radio code and restored the unit without issue, but now it does not accept the code.

 

I have a 2000 986S with PCM (Porsche Communication Management). I have the original radio code card supplied in the owners manual materials. Entering the code results in the same "input code" screen displayed.  

 

What I notice about the information on the screen is that there are choices for PCM and Navigation. The PCM choice is grayed out, and "NAV system" is lit. The original radio code card states PCM, but does not state navigation. I cannot guess why this time should be different after all the times over the years I have had to enter the code. However, I am wondering whether there is another code for the Navigation that is not the same as the PCM code supplied with the original materials?

 

The PCM in general is working; the navigation function is not. I can access all the other screens such as the trip computer and settings, but attempting to bring up navigation results in display of the "input code" screen.

 

Among the materials that included the radio code card is another card by Becker with a serial number. I have not found any way to use that information.

(except for this link - why am I skeptical - http://www.radiocode.ivgsoft.com/radiocode.php?id=682)

 

I am including a photo of the screen. 

 

OK,I just found the FAQ which refers me to the dealer.  What a horrible predicament as I have not been in touch with those people in 16 years.  I still do not see why the code is required now, but if there are no other suggestions, I will grudgingly go visit that place.
