Navigation or extended navigation for C4S Cabrio
I am in the process of finishing my order for me C4S Cabrio (will get in November) There are now two Navigation options:
670 Navigation module for PCM
672 Extended navigation for PCM
this is the Porsche description for extended navigation "extended navigation module with automatic track recording for subsequent backtrack-navigation enables in addition in not acquired areas via gps and compass"
Does anybody know was this means?
