06 Cayenne S - new to me 2 weeks ago.

 

 

Hi, Last 2 days I have seen some odd Sat Nav problems.

 

Yesterday I noticed the icon was off by a few hundred meters in one axis.  The road was being tracked in a straight line but I was passing roads that the map showed as being ahead.  Sometime later the map froze.

 

Searching the threads, I found the status and it showed 0GPS & 0D satellites.

 

Today I drove some 80 miles and on the return leg the status page started to update with a location and the coordinates updated as the car moved.  Then I saw 4 GPS and 2D - the icon moved to the right place on the map.  But only for a few seconds - the map froze.

 

The behavior continued during the journey - coordinates changing - no sats being shown and the icon not inthe righ place on the map.

 

When I got home I removed the spoiler and check the GPS AE - all secure - no loose connections - easy to get at - harder if you lose the screw in the double skin - thank goodness for magnetic tools.

 

I also pulled the PCM - no loose connections.

 

I have reset the PCM with 1, 4 & 8 & ejected the disk and cleaned it

 

Questions:

1 is it one cable run from the GPS AE to the PCM - or is there a break point I might have a loose connection?

2 can the GPS AE be checked with a multimeter or the like (how does the connector come off - I could not remove it...)

3 Is there any other areas I can look or ideas some may have to try to troubleshoot further.

 

I think my next step is to repalce the AE as this seem the most likely culprit and the cheapest item to change.

 

Thoughts anybody?

 

Thanks

 

Simon

      PCM 3.0 Nav Update
      By OscarAH1W
      Can someone validate whether or not the dealer ACTUALLY has to install the PCM 3.0 Nav Update?  Unless there is some voodoo that they have to do with the PIWIS, why do they need 2 hrs of labor to insert a disc and press "enter" a few times??  Seems a waste if you can read directions...  Thanks for any help.

      08.2004 Porsche Cayenne S - upgrade or replace navigation
      By carinabrewer
      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..

      Navigation Map Screen Freezing
      By GSpence2
      Hi All!
       
      I have a question for the group. I noticed today my map screen is freezing on my last stop. The navigation works fine when I put in a new destination and activate the route guidance but when I come to a stop, or slow significantly, the map will default back to my last location. For example, the last destination I entered was Brookdale, NJ and today I put in Brookhaven, NY. The system worked fine but when ever I would slow down significantly, or come to a stop the map would go back to the NJ location and then return to my current route once I was back at speed. Any ideas?Thanks

      Just bought a 997, but not sure if I have nagation or not?
      By christer200
      I just bought a 2006 Carrera 4. It saying PCM on the original bill of sale... does that mean I have navigation? When I press the NAV button it is saying NAV is not available. I think the DVD might be missing and I know I can buy them on Ebay, but where is the actual DVD slot. I downloaded the PCM 2.1 manual but the information is very limited and it doesn't tell me where the actual DVD player is located.  Where is the DVD player?

      Memory 2004 CTT
      By scubatahiti
      I have the following symptoms:
       
      Change to settings (Comfort) reset to default once car is turned off and locked and unlocked.   Time for Clock returns to what was the initial setting on dash and PCM. You can set the clock and drive the car, the clock works until you turn off the car. PCM returns to radio even when i have selected CDC or CD after restarting the  Navigation map not showing correct location. the current location shows i am somewhere in Mexico Date shows 01/01/00. There is no way to change it.  
      Anyone have ideas on what the issue is?
       
      Thanks for your help.
