I just purchased a CD4 changer, mounting bracket for a Cayenne and of course the cartridge for $583.00...

My CS currently has the CDR-23... My question is; does the CS come with the changer cable already installed or do I have to buy the cable from the dealer and tear the car apart installing it...

 

Not positive but I think you need to install the cable. I believe it is a fiber optic cable.

 

Really it all depends on your model year. If its late 04 or newer, the fibre optic cable and the power supply is tucked away in the rear mounting location and it is plug and play for most cars.

To install you have to remove quite a bit of trim but I have information which may help.

 

If you have amplifier and car 2005+ MY cables already in trunk and you do not need bracket. If no amp - I think no cables. Anycase, CD changer must be programmed into Audio system wit porsche tester.

 

Not so, the cdc boots onto MOST bus which sees it as a valid subsystem and headunit sees it.

 

Thanks for the information you sent... It is invaluable... I would think the head unit would recognize the changer as soon as it's plugged into the loop...

 

... it will, it's almost plug and play.

 

Generally CDC-4 is not plug n play!!!! Anycase, if system will start works with changer a lot of errors will present in PCM system, in interface and most ring, can cause unstable working. So visit dealer for sure.

 

Just how many installs are you basing this on ?

 

may be 10 or more during last year, all on pcm2.1, may be 2.0 systems, never on CDR

 

wow, on 2.0 / 2.1 I have never heard of it except on CDR without the CDC being turned on first via PIWIS.

 

In my 04 S, I installed it without issue, plug-n-play! Just make sure you connect the fibre cables properly, you are just adding on to the fibre "ring" of the most system. The changer should come with the fibre cables needed to tap into the amp, then to the CDC.

 

Bull30, who asked the question, is interested in finding out about an installation in a CDR-23 setup not PCM. On 2005 and up the whole thing is setup just waiting for the changer to be plugged in.

 

You are correct... My wife's CS is non-pcm... I'm hoping your info is correct as the install was just made a lot easier...

 

Thanks for the info... I pulled off the right rear access cover and there was the changer bracket with both connectors sitting right there... I looks like an extremely straight forward project...
