Default CDR 23 radio code???

Am about to disconnect the battery to make it safe to remove a door trim -- will wait the required minute so the side air bag doesn't 'blow'.

Car is a 2002 Targa with CDR 23 radio -- will I need a code when I reconnect the battery or is it "self testing"?

Thanks

No code in your Owners Manual?

RennTech.org will get your code for you. It cost to join but it is well worth. They have a lot of tech info including manuals for 996 & accessories, TSB etc.

RennTech can get the code for you most of the time, but it's not guaranteed. You can call Becker and get the code too - I think they charge about $35 for it.

OK -- I'm a Renntech member so I will ask Loren for the code -- but -- after doing some more "threading" I am thinking all CDR23s are the "late type" and that the cdr22 is the one that needs to code -- mine has the amp box in the front trunk back a bit behind the top of the spare wheel.
Any clarification?

CDR-23 (or later):
These radios do not have a security code - that is, not that the user enters.
These radios are security tested on the MOST (fiber optic bus) system to see if they are the "programmed" radio. Only a dealer or shop with a PST2 or PIWIS tester can replace a MOST bus radio (i.e. CDR-23, CDR-24).

Default CDR23 install

I'd like to install a used CDR23 in my '78SC. Is this going to be possible?

If your '78SC has fiber optics it will be. If not, adding a fiber optic system is going to be pretty involved.
