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

yes... the local dealer might give you the code if you dont have one.

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.

for an 02' ?

I thought they had memory in later years?
BTW you can get a little unit that plugs into the cigarrette lighter that will keep the power for the memor "ON"

Marc Gelefsky

03+ has the code "encoded"

ivangene

Thanks Marc, knew it was one of them "new" cars

What a pain in the ***. I am glad I have a 04'.

Marc Gelefsky

Perhaps, but when one wants top Replace the head unit an 02- is nice and easy, newer ones... not so much.

I have that issue with my Cayenne, stinkin MOST bus...

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?

Loren

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).

Thanks Loren -- I just went to the radio code thread you maintain and read that so I cut and came back her to post and ya' beat me -- thanks for the help -- the regulars like me that worry a bit when diving into their cars are given confidence by you generous folk who help us -- thanks again

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.
