PCM 2.1 Update to Level C

Recommended Posts

New here my 1st question. I'm rather baffled by the PCM 2.1 update process. My Gen 1 Cayman S with Bose amp has PCM 2.1 SW version is 3.3 on Level B. I recently tried to  Update to Level C with Multimedia Update disc 000.044.901.40 as per a Tech document I used a few years back to go from A - B with the relevant discs. After the process is finished the Software version is still listed as Level B 05024 ED/4705. The Navigation Map disc 2012 Europe reads fine Anyone else experienced this and if so did you manage to fix it ?

Hello Richard. Thank you for the reply, i've not checked the Navigation numbers i forgot to do it. The 2012 map disc runs fine, I would have updated the Software to Level C but can't establish the disc part no. I thought that the Multimedia disc 000.044.901.40 would do it after running it. I would still like to Update to Level C but now confused if that's even possible, all the posts I have read indicate that the disc MY08 is the one to use.
Regards Simon

The Level C update only updaes the navigation drive, not the PCM head unit. I don't think you can update an early PCM head unit beyond 05024. If you were expecting it to change to 05395, I don't think it will. I have updated a few systems, and none have shown 05395 after updating.

IIRC, the MY2008 map DVD also had the level C update on it, which would have exactly the same effect as the 000.044.901.40 CD.

Thanks Richard, I assumed it would update the head unit.That would explain the fact of not updating as I was using the 2009 map but I had previously had a full set of update discs to change from level A a couple of years back. Next time I'm at Parr Motorsport I will enquire about Level C head unit update, just curious.

Cheers Simon

Hi Richard, that's what I thought but on contacting an online navigation place they said there is a 2014 version that will be the last update for the PCM 2.1

I have ordered a copy and will update here if it actually did update the navigation beyond the 2012 set that I already have installed.

It would be great if Porsche could release the editing tools required to allow third-parties to continue updating the maps beyond 2014 if Porsche have now stopped supporting updates for the PCM 2.1 ........
