PCM2 error

[guymalpass]

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 PCM can 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!

Hi again, just got the PIWIS plugged in now....would anyone mind telling me where I should be looking?!

[guymalpass]

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.

Sorted now, no more error message :-)
