Just be advised that the instructions are for the PCM I unit that has a built in tape drive and needs an external CD drive for the maps.
The PCM II uses the internal CD drive for both Maps & Music CDs and has the ability to show maps even when playing a music CD.
Cables and others stuff I am sure are different.
These are my opinions only from having a 2003 Boxster with PCM II and I know it uses the lastest data bus and fiber optics.
