2008/9 cayenne turbo sat nav questions + general stufg

[poona]

Hi Peeps

Can some of you guys shed some light on when the new sat nav was fitted to the car? Or was it only standard on a turbo S.

What are the must have options?

Whats the aero pack consist of?

Many thanks in advance.

PCM 3 was about 2009, you can see the silver controls and card reader.
Cayenne must have air - all turbos have air, anything else is just nice to have.
