The older CCC nav (which I had in my 06 330i) uses just 1 (non password protected) single layer DVD with map data on which remains in the DVD slot the whole time and the system uses the disc as a ROM device. That's why you have a separate CD slot for music CDs. There is no storage of map data on the system.

The newer CIC nav has only 1 DVD/CD slot and uses 3 x DL DVDs which are copied in full to the HDD system, so the DVDs are redundant after loading onto the system.

It will be the 3D mapping and much higher screen resolution on the CIC version that makes the file sizes so huge compared to the CCC version.

All of this thread is about the CIC version and getting the password for cheap.

The CCC nav discs have been free online for years so there is nothing to 'buy' there.
