I had one in my car before I changed my headunit, although my car was a pre-MOST vehicle.

My Mercedes had a similar system and, though just for iPod, I ended up using the cd changed input.
Replace with another cubby and wired the 2 usb ports

I removed the cd storage and replaced with another cubby and wired the 2 usb ports to the back of the cubby.

The dash speakers I am running directly off the head unit.
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.

I connected the iPhone and put it in there, and it worked great.
bought a new head unit and everything for Sirius from best buy....go into the installation stall and they can't do anything....apparently my 03 996 with the CDR23 is based on a fiber optic system and the installers at best buy don't know what to do and have told me there is nothing that can be done without rewiring the whole car....so...does anybody have an aftermarket stereo in their car? what kind? thx
You can convert your car to a double DIN by moving the AC controls to the lower portion (factory location). There are some good posts out there on this (I know because some day if like to do the same. Miss Bluetooth and Navi)
Kenwood KDC-X996. Absolutely love it! You can match the color to the interior lights almost perfectly. It has exceptional tuneability, pandora, iPod, hands free, Bluetooth, sirius XM ready... All for $200! It doesn't look gaudy, and crutchfield has a harness that will match the car perfectly whether you have Bose, standard, door speakers or not etc.
Edit: posted without reading entire post. Not sure how to overcome the fiber optic thing, but I'm sure it's not too difficult with the right adapters etc...
I am very interested to read your finding about the fiver optic problem
I also have a 2003 and I have never seen a way around it without rewiring and add new amp and all.
Not only the fiber optic make it impossible to use the factory amp, but on top of it, it seems the impedance of the speakers are also problematic to deal with.
Most people rip it all out.
Check out this product from Nav-TV, this is the only interface I have seen that is supposed to interface with the porsche MOST fiber optic system. The downside is the price...for which you might as well as get a new and better amp.

Double din does not solve your most problem ... cheapest way would be to get cdr. Fixed.. there is a place in San Diego that does that .. else new amp and maybe gutting whole system required
If the fiber optic system only feeds a signal to the amps and from the amp to the speakers are standard wires, the rewire is not complicated. You will need to consider a new amp to drive the 6 speakers.
I am with Philooo on this, I have a 2004 (with Bose) and wanted to keep the Bose amp and speakers (with a Kenwood double din).
With the Fiber Optic Most system I believe I would have change the amp too - which makes it much harder to go back to original. You could keep the speakers but have to match their impedance (I think 2 ohms) with the new amp.
Please keep us informed how it goes.
I installed a double din unit last year (Pioneer AVIC 930bt) and had add the amp plus all new speakers. If you do not do the install yourself, I would not use Best Buy, Audio Expess or any other chain store because they do not have the experience to work on these cars.
You will have to bypass the MOST system, however the new sound compared to the OEM CDR is unbelievable. Plus it's great having Nav, Bluetooth, etc.
Also, look on eBay for the Euro Motorspeed site for the harnesses, bezels, cubby shelf, etc that you will need. Loi is the guy to talk to there and has lots of good info.
Good luck!
Simple. From 2003 onward:
To install a standard aftermarket head unit, regardless of size, you'll need to either:
- replace the amp as well. (Nothing else is required. Although many replace speakers, that's not necessary.)
- or install a conversion device that converts the head unit's analog signals in copper wire to the amp's digital fiberoptic signals (the above NAV-TV doesn't list the 996 as a compatible vehicle, but there are likely others).
It's not a single DIN vs. double DIN issue. It's a copper wires vs. fiber optic cables issue. As mentioned above, the fiber optics connect the headunit to the amps and CD-changer. The wiring to the speakers is traditional copper wire. That being said, the speaker impedance for the Bose system isn't compatible with aftermarket systems. I know that there is a MOST-HUR adapter available for the Cayenne that lets you connect an aftermarket headunit to the MOST system. I'm not sure if this adapter works with the 996.
I agree with the comments about having a "big box" store/chain install your system. I'd look for a specialty audio shop that has experience with Porsches. Also, the speakers are really the weakest link in the system that impact sound quality. New speakers make a huge difference.
Good luck with your upgrade!
I just completed doing this as my first mod to my 2004 C4S. I went with a single DIN Pioneer DEH-9400BH. Bluetooth, Pandora, 2 USB, HD Radio, and you can customize to 210,000 colors so it matches well. I replaced the amp with an Alpine MRX-V70 5 channel amp. You basically have to replace the head unit, amp and get an antenna adapter. If you want to keep the factory speakers then you have to do a little wiring if you have the BOSE system. The Subwoofer(s) are 1 ohm each so you must re-wire them in series to get 2 Ohm. I am running the Sub, Doors and Rears off of the Amp. The dash speakers I am running directly off the head unit. However, as the head unit cannot drive 2 ohm (which the dash speakers are) I re-wired them in series as well. I moved the Amp from next to the spare, up to where the 6 disc changer was. I removed the cd storage and replaced with another cubby and wired the 2 usb ports to the back of the cubby. I put the microphone for the phone in one of the switch blanks below the PSM. I'm happy with the results. Although many would argue that the BOSE speakers are not good (please don't turn this thread into that argument), I was really just looking for Ipod connectivity and a few other bells and whistles. Maybe I'll replace the speakers at some point but for now...I'm happy.
NOTE: I went through 3 antenna adapters before I tracked down the right one...It's from Crutchfield and it's this one...
I believe you can call Becker USA and they'll sell you an adapter. I had one in my car before I changed my headunit, although my car was a pre-MOST vehicle. The adapter allowed for direct connection of my iPod/iPhone and it had a little 3.5mm input for Sirius/XM or something else. I believe you can also get an adapter with RCA plugs. I'd call Becker to get the details. If this doesn't work, you could always get a good quality FM modulated unit that connects inline with the FM antenna.
well...that's what i wanted to do to start with...just get the small unit...starmate 8.... but where the hell can i put it? there's no room and it has 3 wires, 2 on one side and 1 on the other...so then i wanted to go the head unit route and ran into the MOST system
When I had my AUX cable installed, I just ran it to the glovebox. I connected the iPhone and put it in there, and it worked great. I could play music directly from the iPhone or I could use Pandora. The downside is that you can't control the iPhone from the headunit or see the song title/track information on the headunit.
sorry to ask again....but you said there could be an RCA plug that has a line in on the other end?.....welll.....mid-way through the post, i just realzed i don't have RCAs on the CDR23....****
Call Becker...they can do a mod to your CDR-23 to give you an Aux input for something like $100...but they have to have your head unit sent in to do it...
Again, Becker can help you better than I can. I believe they have an option that plugs directly into the back of your headunit, and has RCA plugs on the other end. They have other cables too...
Wow - looking at trying to upgrade my Bose system and seeing the complexity here too - sigh...
I went to crutchfield's website and almost everything they offered was "call for details"...
Is there any easy way to add an iPod/iPhone adapter with just a plug from the back, etc?
I recall there is a way to connected RCA through CD input. If your head unit can control Cd changer it can receive RCA input through that. Not sure where I saw that.
I used Crutchfield for my Scosche IPFMRDS system (plug and play) and absolutely love it. Search IPFMRDS for threads on how it works, or shoot me a PM.
Maybe I should post a DIY??
agree with above.. look up my username and you'll find my post about the scosche IPFMRDS. It's great for keeping things stock and using ur iphone. Sound quality is awesome
