Default 2004 996 stereo/ fiber optics conundrum

Hi all! I recently purchased 2004 911 996 CS4 ( with non-Bose stereo system). I tried having a local car stereo business install a Pioneer deck with ApplePlay, but much to my surprise he called me to say he couldn't do the job because all the wiring was fiber optics. Has anybody else had this problem and solved it (especially in the Seattle area)? All I want to do is put in a deck that is Bluetooth capable to play audio from my iPhone... I'd even settle for a deck that only has a hardwire auxiliary port. Any help is appreciated!

Did you ever get clarification on this problem?

The problem is he needs to take the car to a local shop that has a bit more experience/knowledge when it comes to European platforms.

Around 2002, Porsche adopted technology from a fiber-optic system call MOST - Media Oriented Systems Transport. The design allowed complex information to travel from one electrical component to another without the need for proprietary wiring, only a simple send/receive fiber line. The issue the OP is running into is that the factory amplifier communicated with the factory radio over this MOST communication. and since no aftermarket radio uses that tech, the two are incompatible.

In this situation(specifically with the 996) the amplifier needs to be replaced with an appropriate aftermarket. You'll end up investing more than you might otherwise, but if it's done right you'll also get a better sounding and more reliable long-term solution. If you're still iso a solution, send me an email. We're about 3 hours south of the Seattle area, but worth the drive if you're after a quality execution. [email protected]

Those who choose to do a non OEM head unit with the MOST system usually wind up pulling out the Porsche amp and head unit and wire up using a non OEM amp!
