I just replaced a battery and now i cannot enter my navi code. This prevents me from using the radio. I see options but no adjustments. 02 c2 navi pcm1.0. Nav works frin all other functions appear right. Any thoughts.

I have disconnected and reconnected the battery i can enter the pcm code just cant scroll to navi.

 

These units are manufactured jointly by Siemens and Becker, and the only place where you can get the codes required is from the dealer/OPC. The PCM?s require two codes, the ICS/Siemens code and a Becker code. The ICS is the first code requested.

Sorry, the only place you can get a PCM code is from a dealer/OPC.

 

Yeh - thanks for the response! I have both codes! I just cannot scroll to enter the second. The screen shows the line item but it is not accessable for code entry.
