Retrofit Bose + PCM2.1 into Sound Plus with CDR24

[brankota]

Ive obtained a full Bose kit including subwoofer, speakers, full wire harness, PCM, antenna, DVD, telephone module etc...the lot.

I have the sound package plus at the moment and looking for easiest way to retrofit. Has this been done before and are there any instructions, help or pointers?

As a Contributing Member, you can download the TSB which shows the fitting and programming instructions. Go to DIY Tools>Porsche TSBs>987-1 and search for PCM.

Thanks, ive seen the PCM instructions, no problems there, its the BOSE retrofit that I cant find anything on

The Bose system consists of an amplifier plus additional speakers. The PCM / CDR must be coded to use the MOST system to communicate with the amplifier. The Bose amp will also have its own power as well as the speaker output loom which goes to the door, dash and rear speakers in the sub woofer box. You wont find a TSB on retro fitting BOSE because porsche didnt offer it as an aftermarket option. Ideally you need the wiring diagram and the workshop guide for replacing individual components.
