Replacing PCM

My PCM broke and I bought a used one and replaced it.
Most things works just fine but I lost the "individual memory" and "sports chrono" settings etc.
It also nags me with an error on startup about the Navigation. The car it came from had a navigation unit.

My assumption is it would just be to load the codes with a PIWIS and remove the Navigation unit and CD changer it thinks it has?

I had it at a dealer and they say they can't get it to work. If I understand the notes they can't load the codes for some reason. Any ideas?

It probably isn't the sort of thing dealers normally do. 

 

You need to get the coding in the "MOST Installed" section of the PCM to match the hardware attached to the system.  Then run the Handover Routine to reset everything.
