PCM2 upgrade o/s from 2.1 to 3.0


Recommended Posts

:huh: I have a 996 Carrera '03 UK model. I have the PCM2 with version 2.0 (using the main and trip button combination).

My UK Navigation CD was damaged whilst trying to eject it from the CD player which stopped working (another long issue which involved me stripping the CD unit of the PCM back to the laser, and rebuilding it back up).

I'm able to get my hands on a set of PCM CD's dated 2004, but they say I need to have PCM o/s 3.0 for them to work.

Is it possible for the o/s to be updated from v2.0 to v3.0? Is a disk available?

Thanks for any help you can give!

It is possible to update the OS to version 3 there is a TSB detailed the proceedure (13/04 - W522) which is available to contributing members. However the disc with the OS on is part number 000.043.205.46 for non BOSE cars and 000.043.205.50 for BOSE cars. If you have BOSE you will need both discs as you do both upgrades. You will also need the TSB if you are going to do this yourself.

Thanks Nick!. This is a fantastic site, and having made use of the info herein a couple of times, I've happily signed up as a contributing member now.

Do you know if v3.0 provides any additional functionality over v2.0?

I don't think so, other than the new maps work. It should be noted that over here in the US it was a free update. However, things maybe different over there as the warranty obligations are different.

Ironically, my OPC said I needed to buy a new PCM2 unit after I changed the battery which created a system error with the CD changer. I went home, disconnected the -tve terminal of the battery and re-connecting sorted it out (thanks Renntech).

I now need to relaod the NAV disk, however the NAV CD i have is badly scratched so can't be read by the unit (or home computer). Since the 02 disks are obsolete I need to install the 04 versions which need the o/s update to v3.0. I've been back to the OPC today, and they've told me that they don't want to update the software in case the PCM2 unit fails - they'll quite happily sell me some new disks for £500 and install them though!

Seeing as I purchased the car from them only 7 months ago, their approach to after-sales is appalling. I'll seek out another OPC to see if they will be more amenable.

The dealer is really out of his mind. The OS discs can be obtained here

BOSE PCM Disc

Other OS PCM Disc

as you can see, $2.09 each. A slighty inflated price over there!!!

Hi - do those discs work for UK/European PCM units? I have a PCM2 unit with 2003 disks and wanted to upgrade to something more recent...

Many thanks in advance for any suggestions!
