@fred1944 This is the latest V4.76 update for the PCM3.1 V4.XX You will need to burn it to a DVD or possibly a thumb drive as a CD is too small. A map grade is a difficult and expensive upgrade that involves buying a key code tied to your vin from Porsche and paying a dealership with the map update CD's to download them to your PCM with your vin number.

Thank you so very much, If I put this on a DVD will the player in my 981 read the disk? I didn't know if the player was CD or DVD, My current version is 4.73, is there a big difference between the 4.73 and 4,76? Once again, Thank you so much.

Many Thanks and Kudos for the detailed instructions above! Dude, you kick butt here and Thank You for taking the time to post steps and photos...

1. I went with the
   JoyeAuto Apple CarPlay kit
   JoyeAuto Apple CarPlay kit
   (AMZN $439) and during the install, the PCM 3.1 system went into constant reboot mode. Coincidence? Who knows... but I went thru the HDD -> SSD upgrade as described above, and it worked. If anyone wants links to the
   Kingston 240GB SATA SSD
   Kingston 240GB SATA SSD
   I purchased (AMZN $35) the
   WAVLINK hard drive dock
   WAVLINK hard drive dock
   for cloning (AMZN $33), and the process for burning the PCM 4.76 ISO image to a
   DVD-R
   DVD-R
   (using an Apple SuperDrive $79), let me know.
2. I _generally_ have a working system now. The JoyeAuto has a curious screen flicker that is distracting, but it does work. This part of upgrade required my local audio shop to do the install ($600) so this isn't a cheap upgrade, and isn't the easiest as you have to do some "heart and brain bypass" surgery to insert a new sub-board and new video switcher box, but well worth it in my book. The HDD -> SSD upgrade was the really easy and cheap part of my saga. NOTE: By going JoyeAuto CarPlay I lost SiriusXM (no biggie as I now use the SiriusXM app on my phone via CarPlay), and I did also lose AM/FM (only noticeable if the world ends and I somehow need AM news info) but I also lost the Jukebox function. Some have told me that the ZZ2 CarPlay upgrade is a better option? ¯\_(ツ)_/¯

Anyhow, my PCM is now at 4.76 (I only see some minor UI changes in OPTIONS), I still retain the PCM MAP and NAVI functions, I have much clearer PHONE setup for calls (a new mic and clearer audio out of the system speakers with JoyeAuto). And the damn things stopped re-booting (so the fuse is back in, lol). And I have CarPlay.

Holler if I can answer questions or provide links.

I can echo the statements and DIY guides above: I've successfully updated to the JoyeAuto CarPlay unit in my 2014 Cayenne (base). I don't believe this is a DIY project for the feint of heart -- I had a pro car stereo shop do it as it involved dropping in a side board, removing the SXM module, and routing a new mic. Ran me $600 for the install, $439 for the JoyeAuto unit.

Coincidentally, I started getting PCM reboots so I went forward with the HDD -> SSD replacement. Cloning went fine, but the re-install of the PCM 4.76 ISO disc image was problematic -- took 4 different DVD-R's before it would complete the update once the disc was inserted -- but it did eventually complete. My NAVI and MAP functions remains intact. The HDD->SSD upgrade part is the one that's cheap and relatively easy. You get a few UI tweaks for the PCM by going version 4.76 but I honestly can't say that I notice much else. At least you won't reboot and you won't need to pull a fuse nor get greeted with a "battery save" message each morning.

(+): You get CarPlay. Welcome to 2021'ish. Phone calls sound _much_ better and people claim I sound much better as well. The upgrade looks OEM.
(-): You lose SiriusXM (not a big deal IMO because if you want it and choose to subscribe, it's a CarPlay app). You lose Jukebox. I lost AM/FM (only a problem for me if the world comes to an end and I need the AM radio dial) :-)

Hope this is helpful!

NOTE: Some say the ZZ2 CarPlay upgrade is better than JoyeAuto. I'd be tempted to look into it, as I really don't know about the build quality here.

Thanks for everyone who contributed on this thread. I pulled out my old physical drive today. My car was built in Feb 2013 so likely had an original IDE drive but the previous owner had to replace it $$$ because it kept restarting. Imagine that? So I had a SATA drive in the replacement unit.

I cloned it with a SATA dock that also duplicates ($35).


I bought a 125gb Lexar SDD drive for $21.


All went well. The drive took about 20 minutes to copy. I for once didn't break off any tabs and whatnot removing the side trim. This is some super cheap peace of mind.

Hi jsol,
I have the same problem, now the pcm is in emergency update loop. i did clone the hdd to ssd, and there is bad sector on the old drive. the clone was completed. when i plug in the new ssd to pcm and insert cd, it stopped at placeholder (error copying file). i dont know which step i did wrong, can you guide me through. thank you

[QUOTE=jslo;16194989]Recebi a unidade de backup na sexta-feira. Como eu realmente não precisava dele agora, e o vendedor não aceitaria como devolução, usei-o para experimentar algumas coisas diferentes. O que eu aprendi é que com uma unidade boa e funcional, você simplesmente precisa clonar a unidade para sua substituição. Então você pode simplesmente instalá-lo no PCM e tudo funcionará. Não há necessidade de executar o disco de atualização. Eu tentei o software Acronis True Image para clonagem com resultados ruins. Eu recomendaria o Clonezilla com base no sucesso que tive. Vou retirar minha unidade existente novamente, clonar o clone e mantê-lo como backup caso ocorra outra falha no futuro. Seguro barato neste momento.

Outras coisas que aprendi:
você não pode simplesmente trocar uma unidade de outra unidade, não funciona bem.
Existem várias versões de software diferentes. O DVD de atualização examinará sua unidade para determinar qual versão você possui e para qual ela será atualizada.
Há muito menos armazenado na unidade do que eu pensava. Consegui executar o PCM sem uma unidade nele. Navegação e jukebox foram as principais coisas que não funcionaram, mas praticamente todo o resto funcionou normalmente.

Portanto, se você for simplesmente substituir/atualizar uma unidade em funcionamento como manutenção preventiva, faça o seguinte:

• Certifique-se de ter um computador ao qual possa conectar unidades SATA (a maioria dos computadores modernos pode lidar com sata ou você pode obter adaptadores USB e de energia).
• Obtenha um SSD Sata maior do que a capacidade do seu PCM existente. (

  https://www.amazon.com/PNY-CS900-120GB-Internal-Solid/dp/B0722XPTL6/
  )
• Get Clonezilla Live on a bootable USB drive (https://clonezilla.org/)
• Remove your hard drive from your PCM
  • Remove PCM fuse, or disconnect battery (I pull the fuse)
  • Remove side panels from center tunnel (pop off starting from the rear)
  • Remove screws holding PCM in place (T25 bit)
  • The PCM should now be free to slide forward. You may try and slide it forward enough to just remove the hard drive, or attempt to remove the unit entirely - either one is fiddly.
  • The hard drive is at the top of the PCM. Remove the two T8 screws and pry the back of the drive tray up and out of the PCM. Unplug the ribbon connector from the back of the drive, NOT from the PCM end.
• Attach the drive you just removed and the new drive to your PC
• Insira sua unidade USB inicializável do Clonezilla em seu PC e inicialize/reinicialize para iniciar o Clonezilla
  • Você pode ter que entrar na bios e alterar a ordem de inicialização para que seu pc inicialize a partir do usb
• Execute o Clonezilla, escolha clonar de dispositivo para dispositivo, selecione a unidade de origem (do PCM) e o destino (novo SSD)
  • O processo de clonagem levará cerca de 45 minutos a uma hora, então não se preocupe se parecer lento.
• Quando a clonagem estiver concluída, desligue o computador, remova as unidades e reinstale a nova unidade no PCM.
• Eu recomendo testar a unidade antes de abotoar tudo de volta. Basta conectar o fusível de volta e garantir que seu PCM esteja funcionando e, em seguida, montar tudo novamente.
  • Eu também tenho um método de bancada. Se você tiver uma bateria de carro sobressalente, poderá conectar o PCM à alimentação e ao aterramento e executá-lo em sua bancada. Obviamente, qualquer coisa que precise de uma antena não funcionará, mas você poderá realizar funções básicas e verificar se a unidade está funcionando corretamente.

Se tudo isso parece esmagador, estou pensando em oferecer um serviço de atualização. Deixe-me saber se houver interesse e podemos discutir.[/QUOTE

hey guys, my first post here. Is there any download page available for Firmware Update DVD for PCM 3.1? I downloaded one actually, but unfortunately the pcm don't accept it. He declined the media with error message.

The .placeholder issue for me was quite random. After starting with a clean HDD and copying the clone again it suddenly worked. So maybe just try a couple of times or first try with another HDD instead of the SSD?

Make sure to keep an original copy of your disk so you can always go back.

fred1944

I finally got my upgrade done on my PCM and put in a new M2 SSD, all went well, everything seems to be working great and I have 2 clones in my closest for backup. All I purchased was the following
The M2 enclosure is quite sturdy and worked well, I didn't use any software, I put the hard drives in the Clone device I bought and pushed a blue button twice and it did its thing perfectly, I did the same thing again on the Kingston drive and wrapped the original drive and the Kingston drive up and put them up in the closet just in case. All drives except the Kingston were upgraded to Ver. 4.76, I'm a happy camper and all is good.

Look at how many hours my PCM hard rive has logged. That's over 741 years!

I have exactly the same issue , have you been able to fix it ?

does anyone have the exact instructions to create a ssd form scratch using disk genuis and all partition data ?
