Porsche 911 997


Thanks so much for Binize customer David Fertell writing this paper sincerely.


Executive summary


There are a few ways to install an aftermarket stereo into a Porsche 911 997.1 with factory Bose stereo. This document outlines the ‘cheap’ method, using the least expensive components available. I made no provision for steering wheel controls, as my car does not have those.


Thanks to fellow Rennlisters bhvrdr for initially posting about the affordable MOST adaptors, and for shyamvenky for his assistance in figuring out the details of the wiring.


bhvrdr’s thread has most of the details of the parts required, but the details are spread out throughout the thread, which is quite lengthy. So my intention is to consolidate the information I used, as much as possible, into a single post/thread.


I suspect most of these instructions will be similar for 987 cars with Bose. Indeed, the reasoning behind the wiring should be suitable for other cars with MOST fibre optic audio. In fact, I have installed almost exactly the same set up in my 2005 C55 AMG.


As ever, this document details what I did for Porsche 911 997. Open up your own car at your own risk, I take no responsibility for work you may do on your own car. Please feel free to share this document, but only in unaltered format, and with attribution to me.

  1. Aftermarket head unit – personal preference; I chose a Sony because of the rear accessible USB ports so that I could route them where I wanted;
