Yes, only thing in cluster which is not working.
Up to now no one had found a solution without replacing the cluster to 718 version…
and necessary to modify the cluster also due to analog revs are not comparable between turbo charged 718 and naturally aspirated 981…
also ask amp of spp is not fully suitable due to high level signal of pcm4…
changed to mosconi pico 8/10 dsp…

Flash and RAM of multimedia board has to expanded and multimedia board programmed to PCM4 specs,then everything works as from factory.

Price would be around 250 to 350USD depending on hardware inside.
Cluster remains with your original coding,VIN and adaptations since it is located on the mainboard.
All Porsche clusters have multimedia board attached to mainboard via connector so we will only rework the multimedia board while your mainboard remains in original state.

Steps are quite easy:
1) PCM 4 without component protection
2) conversation harness between pcm 3.1 and PCM 4 quadlock
3) usb socket with additional power supply for CarPlay or Porsche / Audi usb hub
4) old ask amp to get plug sockets for connection to mosconi amp (ask amp will have a little sound hissing)
5) cluster firmware upgrade with piwis to establish communication over Can Bus with PCM 4
6) new antenna splitter for dab signal
7) new pdc control modul for display of pdc on pcm4
8) piwis Tester with engineering mode
I have done my first 911 991.1 conversation in 2018 and it still works without any issues (excluding map display in cluster)

If you can disassemble the cluster and ship us only the board then we make it to PCM4 specs.
Price would be around 250 to 350USD depending on hardware inside.

Steps are quite easy:
1) PCM 4 without component protection. I have one planning on using MIB Tool on one I got from EBay
2) conversation harness between pcm 3.1 and PCM 4 quadlock. Created my harness
3) usb socket with additional power supply for CarPlay or Porsche / Audi usb hub. Have hub and usb connectors and cables
4) old ask amp to get plug sockets for connection to mosconi amp (ask amp will have a little sound hissing) using nav Tv zen adapter
5) cluster firmware upgrade with piwis to establish communication over Can Bus with PCM 4. I have. A clone PIWIS 3. Need to figure instructions how to do this.
6) new antenna splitter for dab signal have splitter
7) new pdc control modul for display of pdc on pcm4. What is this? I don’t know what this is or does.
8) piwis Tester with engineering mode. I have a piwis3. How do I know if I have engineering mode?

In case you or the future owner loses the keys to the car,the only way to get replacement is to order from dealer.Since component protection is active in diagnstics(but disabled in PCM4 UI) immobilizer programming will fail.
I would add new gateway with component protection support for PCM4 and online PCM4 component protection programming.

Not sure about the problem with the key.
but I have changed the gateway 2018 first time installing the pcm 4.
but it was not possible for Porsche dealers to remove the cp of the pcm 4 due to the fact, that 981 and 991.1 is not in the database with pcm 4
in case of keys you have to disconnect pcm 4, code the gateway to CDR or nothing and do the rest online…
change of gateway is not necessary

Regular guy cant do that what you just said.
Your cluster has integrated multimedia module on mainboard and display is only separate.
I wouldnt discuss skill of the dealers.
They cant change a tyre without consulting an online manual.

it is not possible to separate the multimedia Modul on the clusters…
only the display…
and the last 3 clusters looked the same
i was working for AVL… seems to be professional enough
)
but you are maybe right on modification of Single chips in cluster…
best way to get map working is to code a 718 cluster…
or to buy a 718 gts 4.0 beside the 3.4 981 and the 991.1 c4 s
thats why I can try all things![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

No, I tried it.
on the picture you see the parts of the cluster.
the display unit has different part numbers.
i have exchanged the display units (multimedia units) in cross way…
718 to 981
and 981 to 718
result:
981 unit still no map
718 unit has maps (also with multimedia unit of 981)
seems to be not working without modification on chips…
