I wonder if the PCM of Porsche 911 (late 991) has been upgraded

Black Carrera's PCM has changed

The other day, suddenly from Porsche 911 (late 991)"Received a danger message"I wrote that.

I've been riding 911 for several years now and it's worse than when I got the danger message the other dayI got on even during a typhoonHowever, I have never received such a dangerous message.

Then I suddenly became interested.

Maybe this is a PCM upgrade? When.

PCM is an abbreviation for Porsche Communication Management, and refers to a function where so-called navigation is displayed.

Black Carrera came back from the car inspection a little while ago last time, but when I recalled it, there were quite a few differences after that.

I feel that such a software update screen has never existed before, but this kind of thing has come to appear ↓

However, the PCM version was not clearly displayed here, so I don't know what the actual current PCM version is.

But there is a clear and definite difference from before.

That was, for example, when I was listening to music and turned up the volume. Until now, even if you turned up the volume, there was no display related to the volume like this ↓

But now, when you change the volume, the volume is visibly displayed like this ↓

This is the story of this part ↓

The PCM of the 992 type Porsche 911 seems to be version 5, so maybe my 991.2 was PCM version 3 so far, and this time it became PCM version 4?

Or, I've heard that 991.2 is PCM4 in the first place, so if so, was there a minor upgrade in the same 4?

I don't know at all ...

However, as of 2021, I've seen the latest PCM version for 991.2 with PCM4.76 somewhere, so I wonder if it's a minor upgrade in PCM version 4.

I don't know what has changed, but something has changed.

I wonder if it was because of that change that I suddenly started receiving dangerous messages. When. Sorry for the inconclusive story (laughs).

I would like to write it again if I know something in the future ^ ^
