Exactly what i needed..thx
after reading the article, i am still confused. 1) since i only have a small yellow connector (see pic)at "c"...that suggests that this car had a cd changer at one time in its life (right??) and that it is missing with the rest of the speaker wiring "b" gone and the rest of "c" wiring gone. ???
2) if cd changer was extracted..would that account for my radio not "turning on" at this time?
3) existing wiring @ "c" does not match with color code 1-6 ??
4) what does the "optical/in&out" do and
5) why is it look different my cdr220

[mikefocke]

Look at the pdf here

2003 CDR23/BOSE/MOST replacement - misc install notes - RennTech.org Forums

See if they match up better.

[Wayne 962]

Is that what you have, a CDR-220? If so, it should match the wiring above. The CDR-220 was the OEM radio from Porsche for the 1999-2002 Boxster & Carrera, according to Becker (who makes the radio).

Or is this a CDR-23?

-Wayne

[WRGREENER]

Ok, what is in the 03 boxster is car is a cdr23 w/pics showing "a" and associated wiring, "b" with no wiring, and "c" with a single yellow connector and wiring. The fact that is is yellow is consistent with your use of a changer. However the color codes are not (see pic & compare to pin nomenclature in article. SINCE B IS MISSING AND ONLY THE ONE YELLOW I SURMISED THAT THIS CAR ONE HAD A CHANGER??

My question about the 220 was precipitated by the fact that the 23 is not turning on at this time (hence question2) and i would consider hooking up my 220. However my 220 has a different looking mate point in the "optical input area than the 23--now that i look closely the opt input does not even fit in the 220 (prob. Old technology with future space provided--germans seem to do that alot
so that adds to the question: What does the optical input do for do for me?

[Wayne 962]

In 2003, Porsche went to the MOST system of communicating with external components in the audio system (phone, amplifier, CD changer, etc.). I haven't played around much with the CDR-23, but I'm thinking if you don't have an external amplifier, then the CDR-200 might still work in the car (presuming that the amp has nothing else it needs to talk to).

I think that the opposite is not true, where the CD-23 would not work in an earlier car, as I believe the radio code is integrated and matched to the gauge cluster.

You can put an aftermarket stereo into the 2003 Boxster, so I would presume that you could hook up an earlier radio as well. But I'm not 100% sure. The ground and power are the same, you'd might have to wire up pin 7 - Orange, as the radio must get it's "power on" signal through the fiber instead.

Ok..been thinkin about this. (remember i just bought this car without a manual, spare tire, tools, bad brake switch, non op radio, and low beam out. So without manual i am fishing for answers. 1) i found a "amplifier"looking unit (center in front of battery compartment)under the bonnet 2) i found a place that looks like it would facilitate a changer (rt side of "amp". I know that the computer box under the front drivers seat was replaced (water infiltration). With that said, i am guessing that the most system controls the works and that it might need some tweaking (programming or what) to get this radio to work? Do i need to add a cd changer in order to make it happy and work? I assume i need a 03 or later changer? Are changer are amp and changer wireless? Same with speaker system?
Finally--i would prefer to use the existing system and not put in the 220.

[Wayne 962]

Okay, so what is the exact problem with the radio then? It may be just that it's code is not synched with the gauge cluster?

-Wayne

[WRGREENER]

The problem is that the head unit will not power-up. At all. Do you think it is a synco prob? If so what do i do to fix?

[Wayne 962]

Check the fuse in the chassis fuse panel (by the driver's left leg). Then check the fuse in the radio. Also check to see if you're getting power to the radio across that big brown wire and the big red one.

-Wayne

[WRGREENER]

Ok, i have power to the unit. So..i did a bench test on the unit; would not power up. I have a second unit, bench tested, it powered up. I hooked up the 2d unit in car. When i first hooked up with optical input connected,-would not power up. Unhooked unit reconnected without o.i. And unit powered up. Then connected o.i. And still power. Screen opens with "porsche" then goes to "protect".
This suggests a trip to the dealer to assign a "new" code for new radio in vehicle electronics memory does this sound correct? Other options ?

[Wayne 962]

Sounds slightly suspicious. I'd hate to see you head to the dealer to sync the cluster and the radio, only to have it stop working again. Frankly, I've never been a fan of these Becker radios - I would recommend dropping $100 or so on a good Pioneer or Sony stereo instead.

Not to hijack this thread, but I have a similar question if anyone reasearching this before me has already figured out.

I have a CD-220 radio with BOSE speakers in back deck and Bose amp next to 6 CD chnager in front trunk.

In looking at my 20 pin plug, in the yellow section which is the first 6 pins, it is currently only uising pin 6 (12v switched power). The Bose system does not appear to be using the output pins. So pins 1-5 are empty. Pins 7-20 are being used for the CD changer.

On the Brown 8 pin plug for speaker output, all 8 are being used.

Does it make sense on a CD-220 that the Bose would take input only from the 8 pin speaker out and use only pin 6 for amp power?

All other pins map ok.

Thanks in advance.

[lilredpo]

Answered my own question.

For my 2002 Boxster S with Bose, on the 20 pin connector, out of pins 1-6, only pin 6 is used to power the amp. The others for 'out' are not needed.

I wired it up last night and everything worked as expected.

Thanks.

[Stiletto Pat]

Wayne and fellow forum readers,

I have an 03 Boxster S with the CDR-23 Radio with the factory Bose System. Occasionally, it gets rather freaky on me. For instance, it has stopped working on a few occasions, and would not respond to the power on/off button, causing me to think it has died, then the next time I start it up, lo and behold it operates just fine. Today, I stopped the car and turned off the ignition, then removed the key, and it promptly started making popping / clicking noises that were being generated in all of the speakers, including the subwoofer. This went on for at least 5 minutes, before it finally stopped. (During this time I was reading the manual, hoping to find the correct fuse to kill the radio...) Also, the radio was powering up without the key in the ignition, which is clearly not normal. While I was looking through the manual, the noises simply stopped. I drove the car home, making several stops, listening to a CD, with no further problems.

Anyone else ever experienced anything like this? I really hate to go through the expense of changing out the audio system. I've been looking for a solution to allow the unit to accept input from an IPOD/Zune device, but I don't really think I want to invest $450 to add that feature to an old stock radio system. So, I really would love to find out if this is an indication that it's about to die, or if it's just a normal ghost in the machine.

Any input would be gladly received.

Thanks,

Pat

My CDR 24 does the "decide not to turn on" thing all the time. See previous rants. No experience with popping sounds.

I'll put in a new radio, but not while I'm in Europe. It's guaranteed to cost more than it's worth, and with my luck I'll find one that won't pull in US frequencies.

It's one of those things that annoys me, but hasn't annoyed me enough yet to drop what I'm doing and put in a new one.

[Wayne 962]

Sorry, I don't have an answer on this one, but I might guess it might have something to do with a signal not properly being received from the MOST bus. Not sure about the clicking noise though - that definitely sounds like a potentially defective radio.

I am trying to re-install a factory CDR23 and Bose amp in my 2004 C4S cabrio that had Bose from new. The previous owner installed an aftermarket Kenwood which has all kinds of flashing light displays and complex menus, which looks awful.


I have the factory mostly hooked back up except for the following:

1. My CDR23 powers up but I get an error 'Protect'. Does the radio need to be coded to the car, and if so, can this be done with Durametric Pro, or only PIWIS/PST2?

2. Cannot locate the antenna cable at the radio end, where does this emerge from the bulkhead?

3. All the speaker wires on the old Bose amp connector have been cut and used to connect to the output of a replacement Alpine amp. I guess this means the Bose 2 ohm speakers have also been replaced with aftermarket? Is it better to retain the Alpine amp instead of replacing the speakers?

4. If I do retain the Alpine amp, will the CDR23 connect to the Alpine amp via the CDR23 speaker outputs, or have these been disabled so it drives only the fiber output? If disabled, is it possible to re-enable via Durametric or PIWIS?

5. If I go ahead and re-install Bose speakers, how many speakers are needed? Does the 04 C4S cabrio only have door speakers or others elsewhere?

[brassyboy]

I too have very similar problems with my cdr23 did any one have a solution
