My navigation system cant seem to acquire sattelites consistently so I want to reboot the PCM system by removing the fuse. I looked on the drivers footwell and saw the fusebox cover and diagram but I cant seem to figure out which fuse needs to be pulled for the PCM. Do any of you know which fuse number it is? Thanks.

Do you have the latest software updates from Porsche?

If so then just disconnect the power cables from the back of the unit for a few minutes. No need to disconnect the antennas.

How can you determine what version of the software is installed? I recently bought the car so I'm not sure about the age of the software currently installed.

I used the instructions but I could not locate the software version. I do know the map DVD is 10.2006. Does anyone know the fuse number I want to try to pull it.

      Hey All,
       
      Brand new here and curious to know if anyone can shed some light for some issues i have. I bought a 2005 Boxster this summer, 95000kms and pristine. I had a shop do an oil service on it and they mentioned that the car looked like it had never even seen rain underneath. That said i have some options that arent working and not sure if they would all be connected some how ??? My cruise control does not work ... my heated seats dont work, rear spoiler as well is not working ..... there is no power by the looks of it ... not sure if this would be a fuse that runs all these? 
       
      From the condition of the car i cant imagine anything serious but i have never owned a Porsche before so i dont want to muck around too much? I have read that if the car has sat for some time with no battery it can unrecognize the features in the car and needs a reboot from the dealer? 
       
      Any insight on this would be so helpful!
       
      Many Thanks

      I have an intermittent static issue. It seems to originate from my center speaker near the clock on my dashboard. When the suspension is lowered it it more prevalent but it also happens before I even start my car. There could be weeks between hearing it and other times it will go on for hours. I suspect I have a loose wire in the amplifier? Is this an issue anyone else has ran into?

      I was checking / fixing fuses, pulling them and putting new that kind of stuff and now my windows do not open and the front light are always on! The fuses are ok but I am wondering if by playing around maybe i messed up a relay or something! I tried to fix the fuses to what they should be, in the past the car ( used ) had fuses too big for what the chart called for, so for example i replaced a 30 for a 10 if a 10 was the one needed etc.

      Greetings all... Over in the Cayenne section there is a post about the PCM System error: UNKNOWN UNKNOWN UNKNOWN UNKNOWN UNKNOWN UNKNOWN UNKNOWN when starting the system up... no ultimate resolution but the consensus for the cause is a break in the line... I have a 2004 Turbo Cab and installed a MoBridge system and have had ZERO issues.  My Parents have a 2004 Turbo Cab where the previous owner went cheap with either the Nav-Tv adapter, the installation, or BOTH (But when you get an otherwise pristine Turbo Cab with 28,000 miles for $42K, you don't nickel and dime).  The installer unplugged the CD changer and pulled the plug off of the fiber optic wires (that plugged into the changer) using a line break splice to plug the two wires together instead of plugging in a loop per the NAV-TV instructions.  I bought both male and female loops so that I could put the vehicle cables into a new plug and install the other plug with the loop.  Since the issue isn't resolved (but the audio works so this has to be the "break") I have to assume it isn't getting a good connection.  Upon closer examination, the fiber optic cable ends on the loops are gold metal and shorter than the plastic ends in the car loop.  This end difference prevents the plastic ends from seating far enough into the plug to make a good connection.  Any advice on how to either replace the ends, or a part number for the original Porsche plug that I could match with a different loop?  I am thinking that Porsche probably have a plug that goes into the CD Changer MOST connector for vehicles that don't have the changer installed...Thanks!!

      Hey guys and gals I have a 2010 Porsche Cayenne base and I’m having trouble connecting my IPhone 6S Plus to my PCM running software version 1.47. Now I know that Apple phones don’t accept the sim access profile, but I can’t figure out how to switch the PCM over to Hands free profile. I went to my local Porsche dealer here in Tucson, AZ today and  I told them that I had read online that they should be able to switch my PCM from SAP to HFP, but after 1 1/2 hours of trying they said that the couldn’t find how to switch it over. Any suggestions? Can it be changed using a durametric? Should I talk to another dealer in Phoenix? Any suggestion or insight will help. Thanks in advance.
