PCM 4.0 in 981 solved

Hi
I have a 981 GT4 which I replaced the PCM 3.1 w/ the PCM 4. Did the cluster flash, etc. and everything is working well except the map in the cluster. I just got a 718 GT 4 cluster, and everything works well w/ the car and PCM 4. Also new LVDS cable PCM4 to cluster.
I need to code the 718 cluster to allow the map to be displayed (because the option doesn't show in the cluster menu). I used PIWIS 2 to do all the prior coding w/ the 981 cluster and PCM 4. Having installed the 718 cluster and by using PIWIS 2, I get "Control unit variant instrument cluster in MCR not found". I am assuming I am getting this error because the 718 cluster is built in 2020 and PIWIS 2 is for units up to 2018. Is this assumption correct? I am waiting for the PIWIS 3 to arrive soon.
Also is it possible to code the car's VIN into this 718 cluster?
Thanks

1) You will need to order this cable from the Porsche dealer (this is a specific Porsche part) 9P3-979-001. The 981 connector wouldn't plug into the PCM 4 (if I remember correctly). The part noted above has the required 90 degree bend that attaches to the PCM 4. This allows the unit to go all the way back (using a straight cable - will interfere w/ the frame of the car).
2) I would definitely not modify the cable. Just order the correct cable from the dealer.
3) Assuming you are using the 9P3-979-001 cable (compatible w/ PCM 4), the cable (Green) end common to the 981 cluster plugs in no problem, but you get no map video signal as others said in prior posts.
4) I purchased a (almost brand new) 718 GT4 cluster to see if the map will be displayed, but the Menu Scope in the cluster doesn't have the map option - so it needs to be programed into the cluster. I have PIWIS 2 which cannot program this model year 2020 cluster thus I am waiting for my PIWIS 3 tester to show up.

on pcm my cluster is oem and my car is 981s. But the pcm shows just cayman. So I got the match 10up amp and nav tv z working. So getting sound via optical cable. The pcm now shows Burmester which is funny since it came from a car with Bose. I can access Burmester settings so for those who have Bose there is an option. I will be ordering the cable for the cluster this week.

On the PIWIS 3 which might be same as PIWIS 2, look for Fahzeaugvariante (its only value passed the "E" listing). You need to be in engineering mode to change this.
Will you use a 718 cluster if the the 981 will not display the maps? Note that the LVDS cable only sends the NAV signal to the cluster nothing else.
BTW on my GT4 I didint have a Bose system (the car at the time only came w/ the STD PCM3.1), so I used the setup as shown below and it sounds really good w/ the stock speakers.

-If the car is 981 and cluster is OEM and you currently using PCM 3.1 - please don't order the LVDS cable from the prior post. That is intended for a retrofitted PCM4 to the cluster.
-If your PCM 3.1 is showing the wrong model, then it must be somewhere in the head unit programing in PIWIS (engineering mode - I think, Maybe there is a code called Fahreugvariante under the PCM control unit). I changed the model logo on the PCM 4 w/ the mib toolbox (via the GEM).
-If your 981 cluster shows the wrong model, code as per the previous post.
