996 pcm 2

Hello, Can anyone help. First my PCM system is running 3.0 system software. The only user instructions I currently have are that of the quick reference PCM. Being a bit of a techno phobe, I could really do with the full user instruction, does anyone know where I can get a copy from. The car is a 911 Carrera 4S on an 04 plate. Thanks in advance for any help given. jb1

There is a US version here, but it should be good enough to answer most questions: https://www.porscheclubgb../forum/tm.aspx?m=293052 You can try a Porsche Centre for a printed copy. They are £9.00+VAT, Part Number WKD 479 720 04 (for a 2004 car), but often out of print I'm afraid. You could also try WKD 479 720 03 (2003) as it would be the same.

Hello Richard, Thanks for your reply, I have managed to pick up a copy now, so all should be OK. Can you tell me, do I need to load the dick in every time I want to use the sat nav or does is it stored in the memory? I do have another question, if I may, I would like to upgrade the system to Bluetooth what would your advise be on this. I have been quoted an all singing and dancing Kenwood system which would mean replacing the existing console (for £907) which I don't really want to do. I have also been quoted a Dension 500s for £576. Also Tooki was mentioned but not quoted. Do you have any thoughts on this. Any help appreciated. jb1

Yes, you need to have the disk in to read the maps, but I seem to recall reading somewhere that you can remove the disk once the route is set. Might be worth a try. Dension, moBridge, Tooki, and Viseeo bluetooth units are expensive (all around the £500 mark), but second hand ones do come up on eBay occasionally. I have heard of people using this, much cheaper unit, but I don't have any experience of it myself: https://www.ebay.co.uk/itm/222630117615

Hello Richard, From what information I have been able to gather so far the Dension 500s, appears to be the better unit to go for, I have seen these for around the £385 mark, not including fitting he quoted £576 fitting included, he also said that I would need to obtain a code number from Porsche at a cost of about £65. Would you know if this would be necessary? Once again all help appreciated. jb1

No, you don't need a code number from Porsche. All these Bluetooth units replace and emulate the CD Changer, so if you don't have one fitted, the system needs to be coded to add one. This has to be done with a Porsche PST2 or PIWIS tester, so maybe that is what he meant. £65 is a bit on the steep side IMO. If you know what you are doing, it takes about 10 minutes. If you are anywhere near me (Maidenhead, Berkshire), I would be happy to do it for you.

Thanks for your reply Richard. I am in St Ives Cambridgeshire so a bit to far, pity. I am at Porsche Cambridge tomorrow for their 70 years of Porsche celebration, maybe I can talk to someone there about it. I'm afraid this is all going over my head now, Is the Porsche PST2 or PIWIS tester something that my local Porsche specialist would have? Thanks again for your help jn1

Any half-respected independent should have a PIWIS tester. Just to try to make it clearer - The PCM has a fibre optic loop cable to connect the external units - Telephone, Amplifier, and CD Changer. (Porsche-speak: the MOST bus). If you add or remove units from the MOST loop, you have to change the settings of the PCM unit to reflect that - Coding. The Dension 'pretends' to be a CD Changer to send sound and control signals round the MOST loop, so the PCM needs to be coded to recognise that a CDC is in the loop. Because the Dension can only use the PCM controls which appear on screen, navigation of iPod/iPhone/mp3 music is very quirky, and takes some getting used to. Changing Playlists, Artists, Albums, etc, is achieved by selecting CD1, CD2, CD3, etc, on the PCM. On the other hand, the Telephone works in exactly the same way as it does with the Porsche phone module.

Hello Richard, It all seems very involved. I was talking to someone the other day, he told me that the cars using the Bose system had the fibre optic cable those using the Porsche system did not use fibre optic is that not so? Thanks jb1

On a MY2003+ car, both Bose (Option Code 680) and Harman (Option 490) are Fibre Optic. Even if you don't have an amplifier at all, a fibre optic connection is still required for Phone and/or CD Changer.

OK Richard thanks for your help, I will talk to my specialist during the coming week about it and see what he has to say.

If you're after a cheap option, I have fitted the system Richard mentions in reply #4 and for the money is really good. My iPhone 6 works perfectly with it for phone calls although to make a call you really need to use the phone so not legal, but answering calls uses the trip computer stalk or the stereo buttons. It plays music perfectly from my phone and gives track details on the PCM display. It does disable the in-built phone though so PCM comes up with error when you turn ignition on which you have to confirm. It's easy to fit where the CD changer is in about half an hour and everything can be put back to original with no trace as well. It's a good cheap option.
