I double checked the options on my car - no Bose upgrade.

I use these guy's stereo parts, did the kid C2 DIN install using their kits, and my C2 also.

I'm considering just replacing the head unit with something after-market.

If you can't just replace the head unit without finding a special adapter.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

So, I'm having the common problems w/ the CDR23 that are so well documented. I'm considering just replacing the head unit with something after-market.
I have read this is more difficult/impossible if the car has Bose speakers. My question is - is the Bose upgrade listed separately as an option? I have the original window sticker, and it lists "hi-fi digital sound", but the word "Bose" does not appear anywhere.
Thanks.
It means it uses the fiber optic cable. Yes, Bose is a separate option.
I have the "hi-fi digital sound" in my 03 also.
If you can't just replace the head unit without finding a special adapter.
Anybody know if there is a howto somewhere regarding an after-market HU I could install, that would possibly bypass the original amp? Something that wouldn't require hacking up the existing wiring?
Call Crutchfield and they can help you with the adapter, the installation kit, and a new head unit. The speakers are the weak link in the system. If you really want to improve the sound quality of your system, then you’ll need new speakers. I went with a Kenwood head unit and a Focal amp and speakers when I upgraded the system in my 996. That was quite a few years ago, and I’m sure there are many great new choices available now. My car had the Bose speaker system prior to the upgrade, and the Focal speakers were a significant improvement.
I double checked the options on my car - no Bose upgrade. So, Crutchfield is wrong about this.
I've read elsewhere that the only way to bypass the factory amp would be to run new speaker wires. Is that correct?
I'm willing to use the factory amp, if it will work w/ a replacement HU. Is there any way to verify the amp is working?
I have the hi fi system on my 04 and kept the amp, change out the head unit and use the MOST converter box, you can find all the info you need in the link posted below. it all works great.

Thanks!
I'm trying to determine if the problem is the HU or the amp; is there an easy way to diagnose it? I have the red light on one of the orange connectors at the amp, for what that's worth...it is lit for about 1 second, goes off for maybe a quarter of a second, then repeats.
It sounds like you’ve verified that Crutchfield is wrong about this.
It would seem to me that this will be a fairly easy installation with a MOST-HUR adapter.
One thing to consider: the thing that makes most aftermarket installations look bad is the trim around the new head unit. Some of them are recessed into the dash, some of them have textures and colors that don’t match the 996 interior. I don’t have a recommendation for you in that regard, I’m just giving you my opinion.
Another thing to note, since you mentioned bluetooth, is that the bluetooth telephone option for most aftermarket systems is fairly useless in a 996, unless you’re siting still in the car. The combination of road noise and engine noise in the cabin of the 996 make it very difficult to have a telephone conversation using bluetooth.
I've learned quite a bit since I first started this thread. I am considering buying a new HU and simply bypassing the amp. So, I'd need to get speaker output from the new HU into the boot to connect to the speakers.
Has anybody done this? Is it difficult to get the wiring in place? Is this feasible, or am I missing something?
Thanks!
There is no easy way for the average DIY'r to test MOST based systems. It's a toss up whether the amp or the HU is malfunctioning. The only way is to take to the dealership, but they'll charge you a pretty penny to diagnose the problem. Lots of people purchase a replacement head unit first and get the RCA pre-amp to MOST unit that has been mentioned in this thread, but remember, there's a chance the amp is malfunctioning. In that case, you'll have to replace the amp too. The speaker level outputs are at the amp. For the HIFI system, you'll need a 6 channel amplifier. This can get pricey. CAI is a good source of information over Crutchfield.
