Instruction Books - Nav System - CD stacker

[Hawke]

I've just purchased a demonstrator Boxter from the local Porsche Dealer. I'm the first owner.

I've gone through all the books, but there is no detail on the Navigation system, or the CD stacker.

I would like to know how the nav system works - I apprecate how intuitive it is - but I'm sure that there is some detail hidden somewhere. I would also like to know how to change the CD easily.

Any pointers?

And if I can ask one more thing. Is there an aftermarket bluetooth phone system that can intergrate into the stereo and or nav system?
