Here's the problem: with an aftermarket Blaupunkt radio, when the car is turned off, there is a momentary "blip" where the radio starts to turn off ("Go..." is visible of the Goodbye message for a moment), but then the radio stays fully powered on. I'm trying to help my friend sort out what may be wrong with his wiring that this would happen. The background: I'm helping a friend sort out the audio system on his 911 - it's a 1997 C4 that had the Hi-Fi sound option. When he purchased the car, there was an aftermarket deck in the dash and the amplifier connector had been by-passed (a total hack-job on the wiring). I repaired all the wiring back to its factory original configuration so that we could re-install the correct Nokia amplifier. At that time, he just wanted speakers on the rear deck. So those were left connceted, and a pre-amp unit (a VC1 from V8A - V8Audio) was installed out-of-sight behind the dash for a minimalist look. The factory radio mounting location was used to relocate the switches from the center console. too. Smash-cut to now, and with some changes in taste, the rear speakers have been removed and speakers are now in the front doors again. Also, a modern Blaupunkt stereo was installed. The "won't turn off" issue is the last thing to sort out this upgrade. I have verified that there is constant power (battery) and Ground at the proper pins of the radio, but what should be the switched ignition signal on pin 7 (in the wiring diagram, this line is labeled as "R" ?) is at a voltage just below battery (Battery=12.8VDC, "Ignition"=12.4VDC). It also measures a momentarily blip at key-off, but then recovers back to ~12VDC almost immediately. Any thoughts on what may be happening are appreciated! What else does the "R" signal line connect to? Could it be the result of a bad ignition switch or power distribution relay? In searching for an answer, those seem to come up as possibilities, but not with the symptoms he's seeing.

There are fuse taps and also pigtail fuses. I like to use the pigtail fuses as they fit the best into the fuse slot in the panel (since they're made from fuses). A spade terminal can work in a pinch, too - just make sure your accessory has an inline fuse on the power line.

Hi Loren, Neither of those worked. I'll include the all the details I pulled from the radio label, maybe I missed something: Large Bar-code serial number - 6625II015006075 Model - CDR220 BE 6625 Serial - 15006075 P/N - 996.645.126.10 This is a 2002 Boxster Thanks, again. Karl

Thanks!

Was helping a friend with his CDR-220 radio project over the weekend. After removing the radio to test some connections, we then reinstalled the radio and got the SAFE message :-) Serial number is 15006075 TIA for your help!

Following the thoughts here and the info at 6speed, I ordered up the Porsche PCM3 iPod/USB/Aux pieces from Suncoast. I should get those parts soon and I'll post on the final results. Probably the toughest part is going to get a dealer around here to enable the PCM for this accessory - none of their parts departments are aware that anything other than the Porsche RF solution is available, right now.

Yup, very familiar with that. I typically leave the GW500 unit behind the radio in the Carrera/Boxster/Caymans. This one doesn't seem to feature CD changer retention, however (only 1 set of MOST lines shown) - so it probably didn't have to pass through to the front trunk.

ps. I would suspect that the shorter the fiber optic cables are, the less problematic, so avoiding longer cables should be paramount. [/b] Actually, that's why I prefer to mount them in the cabin. I can connect right behind the radio. I just don't see many people who want to hang onto a CD changer once they have an iPod/MP3 player in the car :huh: Also, I've found that locating the GW500 in the cabin allows easy access to the iPod, USB stick input and L/R aux input (I put all that in the glovebox). If you're going to be switching between the GW500 and CD changer, you need to have the service mode switch handy. Thanks for the help offered up here!

cant remember if the battery *must* be removed but I wouldn't fear any issue from disconnecting it (assuming you do it right) - the PASM Failure message will come up when you reconnect and start but it will reset and be fine within minutes of driving also, while not knowing what is going on, if your running wires, one may assume your doing something electrical and perhaps that disconnecting the battery is a good idea anyway good luck I certainly don't disconnect an ECUs anymore if the ignition is in the On position - too many Airbag DTCs are set that way - particularly on the newer Volvos (what the heck does an HVAC control panel have to do with the airbag, anyway? :P ). I'm routing the fiber optic lines from a Dension GW500 out to the CD changer in the front trunk for CD changer retention. Thanks, again!

Great, thanks! Would the battery have to be removed to gain access? I hope not (as I know disconnecting the battery causes a whole bunch of trouble codes to be set in various ECUs... :o

there is OEM kit that works well, charges IPOD, USB aux input. cheapest of them all at around $400 But is that actually on the MOST bus, or an FM transmitter? A friend who had the OEM piece (for the PCM3) had the dealer pull it out - he was not happy with the quality of the experience compared to the Dension GW500 he had in his last Cayenne (with PCM2.1).

Does anyone have experience with adding a Dension, Nav-TV or other iPod/aux input solution to the new Cayennes with the PCM3 headunits? Although I saw snippets of news on a solution for the PCM3, there is no direct info at the Nav-TV or Dension sites.

I'm helping out a friend and need to pass a couple of wires between the forward bulkhead/firewall of his 2008 C4S cabrio. Basically, I need to pass those wires from the center console area through to the front trunk. I've searched around here a bit, but haven't found a clear explanation or best practice recommendation. Your suggestions/links are appreciated!

Make your switch connect the Mute pin to Ground. See here (the diagram is numbered looking into the connector on the radio):

This is already from a while ago. Dension products are still available here in the US, just through a different distributor(s).

I have installed a number of Motorola IHF1000 kits into Porsches. The audio performance is excellent, and with your PCM2.1, the radio can mute and the phone audio would then play through the front speakers. Dialing and system control is all voice driven. Search around more for opinions on other options. There are a variety of kits available to meet different needs, too.

I'm a little curious about your statement. The Dension unit requires a similar amount of installation work as the mObridge unit (at least by what I can tell from a set of installation instructions here : http://www.higheroctane.com/images/mObridg...-INSTMAN_v4.pdf ). To my eyes, then, neither the mObridge unit nor the Dension kit have an advantage in regards to installation.

Just as an additional input to this thread... My experience (about 15 cars split across PCM, CDR23 and CDR24 radios) is with the Dension GW500 solution. The Gateway 500 has worked well, and provides the flexibility of iPod, USB and L/R audio inputs. The extra inputs are very helpful for vehicles where I've added both iPod and Satellite radio listening options. I have found that I need to use a ground-loop isolator on the L/R audio input when connecting a satellite radio receiver powered from the vehicle. I'm guessing that either the GW500 or the satellite radio receiver have issues with the alternator whine from the Porsche vehicle power supply. Also, the Panavise mounts work well for mounting the satellite radio receivers, or something like the DICE iPod dock.

The Dension GW500 I put in a friend's Carrera with CDr23 radio last month is working well, too. So there are some options out there. With any MOST-iPod solution, the navigation of the iPod will be limited by the radio interface.

If you have the factory CD changer, you could put a source-switcher on its RCA audio lines, and bring in iPod audio that way (and adding a cradle, charging, etc., if desired). I did this for a friend's '93 nine-eleven Turbo this Winter.

Is it just me, but looking at the description of this device...is it really just an FM modulator? The PCM in the picture of the attached .pdf shows that the radio is in FM-reception mode, and that preset "0" is assigned call letters IPOD. So, the Porsche solution is a slightly gussied up FM modulator? Control of the music from the music player meaning there is no further integration with the headunit? For 350Euro and 2 hours of installation?? Please correct me or help me understand if I'm reading this wrong.

For the CDR23, I would recommend the Dension Gateway 500 unit as well. Done a few of these and they work well. Plus you gain the flexibility of playing audio from an iPod, USB stick, or simple L/R aux. input.

From my experience, this sounds like the MOST ring lines are backwards. The ring is incomplete, then, and all sorts of odd behavior (namely no sound) would occur. The installer should double-check the orientation of the MOST lines, and also whether he installed the GW500 before or after the headunit in the MOST ring. Cayennes like it before the headunit in the ring, and Carreras/Boxsters/Caymans like it after the headunit in the ring. I've put these in a number of Porsches, they have all worked fine. Connection to persistent Battery (rather than switched ignition) is also required.

Be sure to use a handsfree kit designed for the auto environment. I have a number of friends running Porsches with the Motorola IHF1000 bluetooth system integrated in them. Even with the "sport" noise levels in the Porsches, the handsfree call quality is excellent. You're right, though...what is the point of a handsfree kit if no one wants to listen to you talk on it? So get a good one.

The issue was resolved by checking the connector from the iPod cable into the GW500. There was a displaced pin in there. Once that was straightened out and the connector reinserted, the system worked fine. Another thumbs up for the GW500! This one is running v1.05 firmware with a PCM.
