Hello all.


I am the proud new owner of a 2004 Porsche Cayenne S. I know, an oldie but goodie. She is a classic, I could not be more pleased with my purchase. 


I used this forum to help me make the decision. I had a mechanic check her out. She is clean as a whistle.  Looking through the manuals today I see that the original owner kept the maintenance log up to date (how cute is that?!?).  I have never LOVED a car like I love this beast.  I have always considered cars to be utilitarian - they get me from point A to point B..   The minute I drove the Cayenne, I was in love.  It purrs.. it hugs the road, it just moves.  And its so heavy!  I feel so safe.  


All love aside, I was looking for a BMW or Audi with 60-90k miles...  I love german engineering and I really like the navigation in these cars.  I was looking at a 2009 X5 with 80k miles.. it was sitting next to a 2004 Cayenne with 80k miles.  It really was a no-brainer.


The car is spotless, well maintained, and a pleasure to drive.  The only thing I need to figure out is the navigation.  I know, before you all go off and make fun of me for being a newbie, I have read all the articles about the navigation.   I feel like my Nav is on the edge of both the old and new... and I'm not sure what to do about it.  Here are all the places I have found very valuable information - this site being my favorite to peruse, read, and gather information.






A couple of notes - 

- I found the CD's in the car.  The manual says they are from 08.2004.  And the are CDs.  I believe this means I'm on the old system that cannot be updated.  Boo.

- I looked up the PCM version on the panel.  It says version 3.0.  Which I know means that its really 2.1.... Attached is the software versions from the PCM console.. 


Here is why I'm confused - If my software version says it is 3.0, doesn't that mean I'm at PCM 2.1... does this mean that my Cayenne is DVD (vs. CD) ready?  


I am prepared to rip the navigation out and put in something newer so that I can get iPod, Sirius XM, Nav, backup sensors and camera, but my OCD has the better of me.


Which is it - am I able to upgrade my navigation to current times, or should I just replace the unit outright?


Your advise and words of wisdom are greatly appreciated..

Welcome.  I have an '04 turbo.....I have the same unit in my car.  Sadly you don't have the newer PCM.


Is the nav not working at all?  personally I played with the idea so I could get the same luxuries.....ultimately I decided not to.  But my navigation is working.


my thought is leave it alone until it breaks.  It's an older car, but very advanced for the year it was built.  The aftermarket options you have, while offer more features, I feel detract from the unified functionality of the dash and it will be obvious you have shoved an aftermarket unit into a Porsche.


When people ask where is the Bluetooth I simply reply my CTT is about the driving experience, not about talking on my phone or how many cup holders I have.

      I have a 2009 957 3.6l v6 Cayenne. The battery was dead a few days ago so I replaced it. It now starts up just as it should but when run a diagnostic it says the alternator voltage is high reading 14.72. I’m assuming I need to replace the alternator to remedy this. I can’t find any information about replacing the alternator. Has anyone attempted this? It looks like it might be straightforward  but my concern is whether or not the intake manifold has to be removed in order to get clear access. If anyone has any insight on this I would greatly appreciate it.

      Does anyone have a wiring diagram for the seat on a 2008/957 Cayenne which they can let me have?

      I’m trying to chase a fault where the passenger seat will motor up and down and the backrest will adjust forward and aft, but there is no response from the controls to move the seat unit forwards and backwards, or the four-way lumber support control.
      Thanks in anticipation...

      My front wheel was making a rattling noise for about the last week, and this morning as I drove out of my driveway and turned the wheel, I could hear a loud popping noise coming from my wheel whenever I turned. My best guess is that I drove over a pothole and the control arm / bushing moved out of place. Would this be covered under the OE warranty? Or should I take it to a mechanic?

      Hi there, my Cayenne is telling me my driver's side door is open when it is not. This is causing the dome light to stay on. Not sure what the issue is and if can be fixed easily. Any info given is greatly appreciated, thanks!
