Hi there
I had this problem with my 2004 turbo, I took it to my dealers and they said they it would need a whole new PCM unit as the disk drive was also faulty, happily they replaced it under warranty and didnt charge me a thing.

If you mean the small lower lip spoiler, remove the screws from the inside edge near wheel (1 small phillips screw each side) then tug spoiler fromone end to release plastic lugs that locate spoiler into front p.u.

If you don't have a Porsche dealer near you, check eBay for a Nav manual. Your car should have come with one though. Good luck!

remove the plastic trim cover inside at the front where the latch secures to the top of the front screen, then remove the 2 small plugs in the rear interior trims behind rear seats on side panels. Using the special allen key tool turn the catches approx 90 degrees to release the rear of the hood, then simply lift off and back
