PCM2 error

Recommended Posts

Hi I have recently bought a 2005 Boxster with PCM (not sure if 2.0 or 2.1) and Bose speakers. However it doesn't have the DVD navigation unit or a CD changer. The problem is every time I turn the car on an error comes onto the screen "System error: Phone, Navigation System, CD Changer not available." I don't mind not having navigation but I am curious as to whether they were originally sold without the navigation unit? Also whether it is possible to stop the error message coming up at all?

Any help would be greatly appreciated!

I don't think I have ever heard of a UK car being fitted with PCM (2.1 in your case) without navigation. Are you sure the navigation drive isn't fitted. It should be behind a flap in the front boot, in the plastic cover above the tool tray.

Hi, yes it definitely isn't there, the carpet is still in place where the mounting plate is! It doesn't have the phone module under the passenger seat either. I've recently been told the PCMcan be reprogrammed so that it doesn't look for the modules at startup which should hopefully get rid of the error. Does this sound like the PCM has been retrofitted to you?

Guy (Skidd again) - have a look at your factory option codes, this may indicate if it isn't original.

As Richard says, I don't think you could have the PCM on the 987 without Nav. This was only available on the 997 as i recall.

Hi again Skidd! I did look them up online and if I remember right one of the codes was 'digital sound' or something like it. I guessed that was probably the Bose. I'll go over the codes again this evening and see if there were any others.

Thanks again!

It sounds very odd to me. Anyway, you can get the PCM re-coded to remove the options you haven't got fitted.

If you are anywhere near me I would be happy to do it for you, but I couldn't do it for a couple of weeks. Drop me a PM if I can help.

Hi Richard, thankyou for the offer it is very much appreciated. I've actually already booked it in with CMS Porsche in Telford on Friday (I live near Stafford). I must say the excellent forum support, easily available parts diagrams and TSB's are making Porsche ownership surprisingly practical!

Its also looking like the PCM isn't original, I only have 680 out of those codes you posted skids. The PCM in PIWIS also says something about 997 so presumably that's where its from.

      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?

      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.

      I replced the CDR23 with Seicane Android HU.  It comes with Canbus adapter and I purchaed MOST adapter with it to make it work with factory Bose amp.
      The unit powers up fine, but the MOST adapter needs to have power to work.  Any suggestion where can I connect the three wires listed in the pic to?  I assume the main socket that was connected to the CDR23 has power, but don’t know which wire is which.  How easy would it be to get power from lighter adapter aux?  I am planning to replace that lighter adapter with USB port for the HU as well.
       
      Thanks

      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.
