I have an '04 955 Cayenne S that has PCM 6635 SW version 3.0 (there is NO DVD player located under the drivers seat..RHD)..Whenever I press the NAV button on the head unit all I get is 'SYSTEM STARTING' but nothing ever happens...Can anyone possibly give me some advice on.
1..Do I need to reinstall the maps CD.
2..Where I can locate maps for AUSTRALIA.
3..Am I able to use the GSM system with the SIM card tray provided.

Any information would be greatly appreciated.

MAD PROPS FOR ANYONE THAT CAN HELP ME.
