PCM loses navigation & stereo settings

if your system has the memory function as indicated by a switch of memory positions on the passenger door, you may need to set one of those switches also. I seem to recall that this series of switches control some of the memory settings for the radio, climates, etc. My Cayenne has this. You need to access the setting using the controls on the stalk and then set an appropriate memory button on the passenger door and then tie that to your key.
