I would like to replace the BOSE/MOST CDR24 in my 987 with a secondhand PCM head unit taken from a 997. The main goal is to use PCM to operate a Dension IPod controller which I have yet to install, but I'd like any other "standard" functionality of PCM to work too.

The PCM part number is 997 642 141 02.

Is this a straight plug and play swap, or is there programming needed at the dealer?

Any guides on what steps are needed?

Thanks.

 

Yes; when I did mine, the dealer had to use PIWIS II. It took the tech 15 minutes - no charge.
