I have a 2003 Boxster with the CDR23 radio and external amplifier mounted in the front trunk. There are two multi-pin connectors, a fiber optic connector and an antenna connector on the rear of the head unit. The display on the head unit in the car seems to be fine as the display appears to be working as it should. The problem is no sound out of any speakers. The problem was intermittent for quite a while as sometimes when I started the car I would have sound from the speakers and other times no sound. Sometimes I would be driving and the sound would suddenly just quit. Now there is no sound at all, but the head unit display still appears to be working ok. Does anyone have any suggestions as to what might be the problem?
Just finished (January 2014) an audio upgrade to a '99 C4 Cab. Thought I would document it for future reference.

Hi. My Bose amp is bad on my '06 Cayenne S w/ navigation, so I'm going to go ahead and upgrade the head unit to a Pioneer AVIC-1040 and go to an aftermarket amp. I searched the forums, but couldn't find this posted (though I'm guessing it has before). Any recommendations for an amp and how many channels (5?)? What's the best way to group the factory speakers into the amp channels? What's the best way to retain the steering wheel controls?thanks in advance,Kevin
Yes, there are cheap aux cables available on ebay, Crutchfield (Blaupunkt cable), and even direct from Becker. There are also ipod adapters available from Crutchfield (Blau cable $5), Becker (over $100), and Scoshe ($180). I think the only one that offers both aux and ipod is the Scoshe and it's $180 and you would have to adapt it to the Porsche pinouts.
Blaupunkt ipod $5:
The reason I started this thread is that I wanted to add both AUX and ipod capability. I wanted to be able to plug in my ipod or plug in a smart phone. I also wanted the ipod connection to charge my ipod. A couple of years ago I bought such an adapter off of ebay for my Accord, it was plug and play and cost about $75. I went on ebay and found that same adapter but they didn't offer it for Porsche. They did, however, offer it for Audi and VW. It was listed for $29 so I figured I would take a chance and try to get it to work with the Becker CDR-220.
I'm not trying to promote their adapter, just trying to help out those that are looking to add ipod with charge capability and AUX.
I cross referenced the VW/Audi pinouts to the Porsche CDR-220 pinous and got it to work. The key thing is that VW/Audi have all of their CD changer pins on the blue mini iso connector. Porsche moved these over to the green mini iso. See images borrowed from TDIClub.
Blue mini iso as it is wired by Axxess for use on VW:
Pin#13 - Data To Changer - Axxess wire Yellow
Pin #15 - Data Clock To Changer - Axxess wire Blue
Pin #14 - Data From Changer - Axxess wire Brown
Pin #16 - Power to Changer (+12) Axxess wire Grey
Pin #20 - Right Audio - Axxess wire White
Piin #17 - Power Control -Axxess wire Green
Pin #18 - Audio Ground Axxess wire Black
Pin #19 - Left Audio - Axxess wire Red
Removed the Yellow, Blue, Brown, Grey, and Green wires/pins from the Blue mini iso.
I obtained a green mini iso and plugged the pins in as follows:
Pin #10 - Yellow wire from Axxess adapter (cdr-220 data)
Pin # 7 - Green wire from Axxess adapter (cdr-220 bus-on)
Pin #12 - Brown wire from Axxess adapter (cdr-220 changer reset)
Pin #9 - Left blank (but I'm pretty sure this is ground and the ground wire could have gone here. I chose to attach it to the radio body instead)
Pin #11 - Blue wire from Axxess adapter (cdr-220 clock)
Pin #8 - Grey wire from Axxess adapter (battery or power 12v)
FYI, the 3rd image below is of the pinouts for the VW radio...NOT THE PORSCHE. http://www.modifiedlife.com/2002-volkswagen-jetta-car-radio-wiring-schematic-for-monsoon-audio/
I used this image to cross reference to the CDR-220 pinout provided by the pelicanparts forum under 986 diy radio. http://www.pelicanpa...dio_Install.htm
I sent an email to tech support at Axxess to let them know of the pinouts I used and suggested they make a version for the Porsche as I know there's interest on this forum. Hopefully they'll work something up.
