So.. (as the current idiom appears to be)...
Apparently I have PCM4 (its a MY17 petrol S first registered 1 March 16) for which I requested the current upgrade which I was told was no problem. The work was allegedly carried out at the end of Feb and according to their invoice took 20 minutes!
I've only ever had one upgrade prior to this which was after the first service.
Having seen the examples on this thread, and suspecting that what I had should be better than it is, on 20 March I asked them to check the Version No. of the upgrade. Despite several nudges they appeared to struggled to find the information and emailed to say that this morning.
So I thought I might lend a hand.
I sent the Porsche code for a Nav update from the Porsche website and copied the 'January' examples and report of that experience from earlier in this thread together with pics of my current 'newly upgraded' setup. I also gave them an example of the dire state of what my 'updrade' delivers by pointing out that it failed to recognise the new ring road to Bristol Airport which opened in January 17!
This is their response.
Good afternoon....
Many thanks for previous email.
As you may be aware software updates and navigation updates are two different tasks.
I can confirm that your navigation display on your screen (carried out in February), is the latest 2018 update that is available to us. I am sorry to hear it did not recognise the new area you were driving though, please be aware that the information contained in updates can be 12-18 months prior to the production of the update, which may explain why some map features are not shown.
Your vehicle history also shows that software updates have taken place as well as the navigation updates. This shows that your software is also completely up to date.
The part number 95804490550 that you supplied us is a navigation update for PCM 3.1. and is not valid for your vehicle which has PCM 4.
The PCM software version is vehicle is running is 0807.
The sat navigation version is running 2017/2018.
There are no part number represented on these software update, as they are no longer a CD update like the previous PMC 3.1 would have been.
I accept my error re 95804490550 but it would seem bizarre that PCM 3 and 3.1 get 2019 when PCM 4 doesn't!
As the whole Nav upgrade appears to be one contradictory and confusing mess all comment would be gratefully received. For example, where does one go to verify what should be? M
