cdr23 problem


Recommended Posts

Hi, firstly hello to all, i'm new to the world of Porsche, just bought a '03 Boxster for the wife (huge brownie points...!!!)

when bought, it had an 'Alpine' single din headunit fitted and it appeared that the speaker wires to the amp had been cut and wired direct to the headunit...

I sourced a cdr23 got the speaker wires re connected and had it 'coded' to the car at Porsche main dealer, but no sound..!

believing it could be the Amp or maybe the CD changer causing a problem, it was tested again at Porsche who were very helpful (Porsche Silverstone at Towcester) and it was determined that the optical link was OK but it showed an error either with the amp or CD changer, using the software, the amp and CD changer were removed from the computer and we wired the speakers direct to the back of the headunit....but still no sound

is there an answer to this.....

please help, i don't want to re-fit the Alpine...if i have to i would like to fit a Becker Traffic Pro if i can't use the cdr23

The original (CDC-4) CD-changer would not likely have worked with the 3rd party head. CDC-4 is fiber optic only.

See what model CD-changer you have to be sure.

Then I would double check that they added all your options back into the MOST gateway config.

Those amps are know to go bad but both amp and CD-changer - that would be unusual.

It is a CDC4, which is not powering up... The amp is I'm 99% certain faulty, rather than throw money at new ones, considering there may be other issues that arise in the sysytem, I would rather, if possible just use a CDR23 with speakers only.... Can this be done..?

Or if not, then fit a Becker traffic pro direct to speakers or a Becker Mexico....??

Is the cdr23 a ' fit with amp' only head unit or can it run 'standalone'...??

From another thread, here is the Pin diagram for a CDR-24. Not sure if they are the same pins or if they are functional when the head unit was sold including an Amplifier option. They may help.

I have been looking for sourcing options for Becker in the US and have not found an authorized dealer that stocks the Traffic Pro. It seems to include all my requirements (aux input for IPOD, Bluetooth, etc.) and keeps the stock look, but have not had luck finding it.

Most forum members have given me advice to go to another brand head unit.

hope you solve your problem, and if you do it with the Traffic Pro... let me know where you found the Becker head unit.
