Head Unit replacement - CDR23
 

Hey guys,
Recently we have replaced the wife's 08 Lexus IS250 with a 06 Cayenne S (new baby and she needed the room, I just needed a Porsche). I've searched for topics on replacement for this radio unit that has the Bose speakers but I'm getting mixed answers. Supposedly this is the fiber optic speakers but the headunit can be replaced with an adaptor to run the Bose speakers.....? This is the wifes car and she wants the Navi w/iPod and backup camera so we are looking at the Pioneer unit. Since she doesn't really care to much about all the additonal stuff, such as better speakers, we are looking at replacing just the headunit.

So, is this possible or not?

It is possible but in addition to buying the pioneer head unit you have to buy a box kinda like a converter box for the fiber optic to hook up to the pioneer. Last I checked it was around $350...i believe this is it Soundgate CANPULSE4

it will be a bit more expensive but...

Also, don't forget about the dash mount kit. It's supposed to be pretty difficult to actually find one that looks stockish :(

they have that also... last time I checked it was a few weeks out. you should ask why they built this unit...

...Well long story short, the PCM3 has been problematic, so the owner said screw it... and wah lah... head unit replacement module

I understood what he meant, the unit that I listed takes all the fun out of it, and trust me when I say I have done many cayenne radio replacements... this is cake walk... and for the cayenne they do have the bezel, sports cars were awaiting the bezel. Also they have a nice rear camera for the vehicle that is integrated, just very labor/time consuming.

also the unit I listed works on all bose equiped fiber optic speakers LOL... alright Bose amp'd system

Do you have a link/picture of the bezel? I'd like to put an aftermarket HU in my CTT but the biggest thing holding me back is the double din fascia.

Is the sound quality any better or worse when using one of these conversion units to use an aftermarket HU?

sound quality is about the same seeing that both an aftermarket and the factory unit put out the same frequencies 20-20k Hz. this saves the trouble of splicing into the wiring from the output of the factory amp maintaining the factory integrity of the wiring. I will see if there is any pictures on line of it, actually I think there is a video I will look for it.

Husky, I wouldn't let that deter ya

complete with video and pictures.

I'm facing the same issue as eds123 with my '04 Cayenne S. CDR23 went out, and I don't see the point in replacing with the same unit. I was planning on the Kenwood 8120, but Soundgate tech supports says no go for the Canpulse 4, that it won't convert the output to the factory Bose amp. Is it possible the tech is mistaken? Is my only choice to replace the amp as well? Appreciate your expertise, gang!

I think the 04 had a different optical Most connector, but I will find out tomorrow.

There was a difference b/w '04 & '05 according to NAV-TV folks. They don't support earlier than '05 as a result, but he didn't know the exact reason why. Thing about Soundgate was that their tech said Canpulse 4 wouldn't convert any analog signal to optical, so wouldn't work with any factory Bose amp that uses optical inputs, regardless of vehicle year. I told him I had heard otherwise, but the conversation wasn't going anywhere. I'll replace the amp if necessary, but would be great if I could keep as much of the factory setup as possible in place since super hi-fi sound isn't my main objective (and would more than double the price of the job). Also, I imagine a compatible amp will be pretty big bucks since there appear to be so many channels (4 each L&R, phantom center, sub-w, by my count). I'm rambling... Never realized how big an ordeal this would become. Can't tell you how much I appreciate your input!

I really didn't have time to look today, plus Porsche doesn't show the internals of their modules on the tech manuals, however, the infotainment CAN is not hooked directly to the steering wheel control module. From what I seen, was that the signals from the switch are in the CAN comfort bus, which is translated in the instrument cluster over to the CAN infotainment bus and behind the radio.

If you do not have the BOSE system then you can just hook up the speakers to the aftemarket radio, if you have the BOSE system then it is on the fiber optic line and you will need to add an amp.

As far as getting the steering wheel controls for the radio, I seen that the horn and airbag have their own dedicated wires, but did not see the dedicated wires for the push buttons of the radio. If, and I say if because I really didn't have the time to research further, that the 2 wires listed as steering wheel data are for the controls, THEN... to test I would disconnect the two data wires, and see if anything else was affected. if not, I would hook up a scope and start pressing the buttons to see what the resistance of each switch is and then hook up a PAC universal steering wheel control via the resistor pack.

Again, I did not research it heavily, the two wires I was referring to were in the steering wheel control module, and in the F plug.

hope that helps, that is really as far as I can go on this unless I have the vehicle in front of me.

Many thanks. I do have Bose, so will need to replace the amp. I'll get to it this week and let you know what I find.

No problem

Hey keep us updated!! I have a cd23 in my 05 S and still have my double din eclipse nav from my old car. If its just a matter of installing a 6 channel amp and slapping the unit in, I would do it in a heart beat. Thanks for the great input guys!

Along the vain of this thread, I have been looking at a 2008 or 2009 cayenne without the pcm or Bose but considering adding the Kenwood system with gps, xm... or just adding a XM kit to the existing unit. Do any of you know what will be required to add the XM antenna? I think that I have read that porsche puts them in the rear spoiler at the factory? If so, do they all have them in the spoiler or will I have to add an antenna? Any other advice?

The antenna plug will be different so you'll have to use the Kenwood one.

Nice thread..

Any of you have pictures of your aftermarket installations (Kenwood or anything else)? I have a CDR23 that I'd like to add satellite and ipod functionality to and would like to just change the head unit..

Any updates? Is this even possible?? Any how to's maybe??
Thanks guys!

Nice work, is the frame for the Alpine custom or does it come with the player?

all hand built out of ABS plastic.

Really sharp. Will the display still work above the speedometer?

Not for audio information, once the aftermarket goes in, it gets coded for no radio in the gateway and cluster that way there is no blank screen for audio on the cluster. Need to use the Porsche computer for it though. I know Kenwood is coming out with a nice voice activated unit soon.

I know this thread has long been dead, but has there been anything new of recent? I have an 2006 V6 with Bose. But its non navi. The basic headunit is so outdated so i plan on installing the Pioneer AVICZ130. Ive been reading in the other porsche model sections, specifically someone's thread for the 997, and they were able to just add the aftermarket headunit, bypass(skip over) the factory bose amp and connect straight to the factory bose speakers. Is this possible??

Just completed putting in a AVIC-X930BT - ran wires back to the speaker harness from the old bose amp. The new head unit has plenty of power. Ran the front center and rear speakers in series with the front speakers. Even put in a back-up camera - way cool - should have done this a long time ago. Not an easy project - but worth it!

Looks stock with the new head unit - bought the adapter from a place in England...

twilight! Just what i wanted to hear! Do you an email or number i can reach you at? I have questions. I can't PM on here yet because i don't have a high enough post count. Let me know. Thanks

Any users have youtube links to this? I've seen the Dynavin and Chinese stereo, but am interested in a Kenwood or Alpine replacement for the stock Bose head (and amp, if necessary). I really only need an aux and Bluetooth if there is a "cheap" way to that route.
