PCM2 telephone module kit part #s

Recommended Posts


I have the chance of a PCM2 telephone module (part # 996.642.207.01), and I called my OPC to determine if it was compatible with my PCM2 unit (part #996.642.214.03), but as is usual for OPC, they always seem to want to complicate things, so they couldn't answer either way.

They told me the phone module comes as an aftermarket kit, which amongst other things is an "optical wave guide", which is unique to every car (!!). No-one seems to even know what this thing does! They have taken my chassis number and said they will get back to me, which going by previous experience won't be anytime soon!

I have a source for a few of the other bits that might be part of the kit, inc. cables, brackets etc.

Can anyone give me a breakdown of the individual parts and their part numbers for the telephone module after-market kit?

Thanks in advance,


Sorry, just realised I've posted this in the 996 section, should be the Boxster section! PCM unit came from a 996, but I have an MY03 Boxster

Have a look at Boxster TSB 3/04 Telephone Module (Option I No. 666) (dated 4-1-04). It will show you how to check and which optical wave guide to order. As well it has a complete parts breakdown for that option. 996 642 207 01 has been replaced by 996 642 207 02 but the 01 version should still work on PCM2.0.

Hi Loren,

Yes, I spotted that TSB just after posting! It made me realise the module doesn't plug directly into the PCM2 unit, but is located behind the seat! I always thought the module would be there to allow easy connection of the handset, but maybe not (I don't see a handset mentioned in the kit). I figured out the optical wave guide is for the MOST cable to route to the module.

Do Porsche allow for the individual parts of the retro-fit kit to be ordered separately? I',m beginning to think it might be too much work for too little return, what with new blue tooth technology etc!
