CDR23 To Changer Connections (03S)

[ukchris]

Can anyone confirm what connections run between the CDR23 and the appropriate changer? Is the audio carried by fiber or regular RCA cables? I was wondering if installing a CD changer might allow me to do the Aux In "trick" where you allow the CDR23 to control the changer but feed the actual audio from another device.

I have an 03 Boxster S with CDR23 and Bose if it is relevant.

Thanks, Chris.

On the CDR 23 the audio and control signals are digital via the fiber cable. Good thought, but not gonna work.

Oh well, back to battling with my FM modulator! Thanks for the reply.

Use an inline FM modulator. It is the best of a bad solution. Here is one from Crutchfield for $29.00

I have that very same one, and a Ground Loop do-dah too. Sound levels are low though so I need to crank up the CDR23 which is ok, until I decide to put a CD in then I blow my ears out. I need to fiddle with the gain on it although I have it high, that and my line out volume. I seem to be losing some of the highs in MP3 files so I'm also re-encoding at 192kbps instead of 128 to see if that helps.

Then I need to check the wiring running from the front trunk to the modulator to make sure it isn't picking up any more interference than I'm forced to deal with. A slow plod and too much time spent upside down in the footwell but I'm getting there!

These links are interesting too http://www.ppbb.com/scgi-bin/boards/986/main.pl?read=1032775 I've emaile Oasis for more information on this USB/Aux adapter.

I posted an idea similar to ukchris' not too long ago and have recently decided to buy a CDC-4 and harness to see if it would work. I knew the audio came through the optical feed; are you absolutely sure the changer data bus runs through the same?

Perhaps someone has a photo/diagram of the changer harness to help solve this. :)

When you add a changer I assume the MOST configuration has to be updated so that the car/head unit allows it to work. So, if Becker made an Aux adapter for the CDR230 wouldn't it be fair to assume all you'd need is access to a PST2 to enable it and make it work?

I think I'll mail Becker. Last time I talked to them they just said it couldn't be done as Porsche had made it impossible, it seemed they were implying it could be done uner other circumstances, maybe enabling through the PST2 was what they were referring to?
