I have retrofitted it on my 2009 Cayenne PCM3; It works great !
The only complaint I have is that it lacks the new standard 5V charging, Hence it would not charge the 3G and any newer iPods to come.
Luckily, the UMS package also includes a USB connector for removable media and an 3.5mm AUX connector, so if if your iPhone is running low you can charge it via the USB connector (but lose control of course)
I'll post some photos shortly.

? Did you retrofit the iPod adapter on your existing PCM3 in the Cayenne?
Thats a different setup than ordering a 997 with PCM3 and iPod adapter, which is hardwired, from what I understand.
Doesn't this imply the charging scheme is not standard at all, if they just changed the so-called standard?

USB Charge...
Minok,
Both the 997 and the Cayenne have an OPTIONAL iPod adapter.
If you don't order your vehicle with one, it can be retrofitted to the 997 in a similar fashion as the 955 Cayenne.
The difference between the two kits is the center console plastic adapter that holds the iPod, USB and AUX connectors. Everything else, including the 3 meter wiring is identical.
As for the Charging system:
until now, all iPods had two methods of charging:
FireWire charging and USB charging. FireWire charging accepted up to +30V, which made it perfect for an automotive use. Many interface manufacturers used this charging input and supplied a switched +12V to charge the iPod.
However, starting with the 3G and in all future models, the FireWire input was dropped and the only was to charge the iPod / iPhone is via +5V USB power, which required not only a different pin but also some resistors on the USB TX / RX pins. Unfortunately, it seems that the Porsche iPod interface was designed long before the switch to USB charging was confirmed.
This problem is common with many interfaces on the market including our current OPi-P, which will be resolved on the next revision.

im sure we can figure out a way to mod the stock system to make it charge aswell.. looking forward to your pics nav-tv

Daytona:
The 997 (including the Carrera) PCM3 has the same guts. I now for a fact that the iPod kit and the Bluetooth retrofit work on a 997, although I am only 95% certain that the Backup Camera will work on a 997 as well.

Usb Charge:
SEI,
Since the current setup with the PCM3 center console dock is: USB connector for removable media, 3.5mm AUX analog audio input, and a 9-pin mini-din iPod connector with FireWire charging, analog audio and UART control,
I see 3 scenarios:
1. Porsche (Via Harman Becker) will write software to enable iPod control via USB rather then via UART (current operation mode) and release a new iPod harness that will plug into the USB connector in the center console (and perhaps AUX if their USB chipset does not support Digital Audio streaming). Knowing Porsche, It would not happen too fast.
My prediction: 20% probability it will ever occur, and if it will: 6 to 12 months before release.
2. Porsche will release a revised center console dock assembly that will draw it's +5V charge from the USB connector and re-pin the mini-din connector, and will also release a new iPod cable.
Prediction: 50% probability, same 6-12 months. Less logistics, only 2 parts to replace and no need to write new software.
3. Aftermarket companies will take the initiative to perform action #2 (see above). Probability: 90%, Timeframe: 2-3 months.

yeah i highly doubt porsche will do any fixes for the universal audio input.. so i guess i'll have to wait for aftermarket companies to fix this (or just buy an old ipod i guess).

Just to clarify:
1. The only iPod affected today is the iPhone 3G. Future iPhones / iPods will be affected as well.
2. All features still work great, even on a 3G, But it simply won't charge.

So what was the thinking, if we can speculate, at Apple, to drop the high-voltage power input line from their iPod docking connector on the 3G and onward? Did they add some super new feature that they needed those contacts on the connector? On the face of it, it seems like a dumb idea. I guess I'm happy with my old iPod Photo with its Firewire charging capability. Between that and a huge memory stick for the USB port, I'm set. By the way, option 4, of course, is for home users to hack and rewire their iPod connection to put the proper charging voltage on the proper pin of the iPod dock connector cable. That said, replacement of the cable is probably all it takes. a 12v to 5v dc regulator is tiny and can be tucked away as easily as a penny.
My understanding, from reading about the iPod add-on interface for the 997 on some board, was that it was an FM modulated connection to the PCM. I'd assumed the factory ordered option was not just that FM modulated solution installed at the factory, but a fully hardwired interface.... I was under the impression that there were two different implmentations of getting an iPod interface: the FM add on for older 997's and the factory installed 997.2 solution.

Since Apple is probably more secretive then the MI6 and Mossad combined, we can only speculate.
First, they dropped firewire support completely. I guess they concluded that USB is the connectivity standard and not firewire. Remember, FireWire is something that both Apple and Sony pioneered and pushed.
Second, a regular 5V regulator will not do. it needs special protection on short circuit as well as special EMC protection. there are power supplies dedicated for USB devices.
In general, I agree, a new cable with a built in regulator will do the trick.
I have to stress that this is a problem that 90% of automotive iPod interfaces is suffering from currently. While we are working on a solution, it will probably won't be around for another 30-60 days.
