Hi everyone, first I would like to say thanks for a great site!

I have a 2009 Cayenne V6 with a PCM system with Navigation. The car is all factory components with no modifications. It has a single DVD player and it is not a Bose audio system. There is a universal audio interface in the center console with iPod, AUX, and USB connections. According to the SET PCM screen, the PCM system version is V1.40. I assume this is the software version as I saw multiple references on this site to more recent (V2, V2.1) PCM systems on cars that were older than mine.

A couple days ago, the iPod connection started misbehaving. When you play audio through the iPod connector, the audio level is very low and tinny, almost like a pre-amp is not working. I tried using the AUX input with the same result. I tried various iPods/iPhones with the same result. When I connect a USB device, the audio is normal, as is the audio for the radio and the CD player. I reset the PCM settings via the SET PCM screen but that did not help.

I read through the forum, but did not find any posts with the same issue. I found one post that referred to a PCM reset procedure involving the MAIN and INFO buttons and a 1+4+8 button press on a keypad, but I don't understand this as I don't have a MAIN button nor a keypad. How does one reset this PCM system?

Is there a pre-amp for the iPod and AUX inputs that may have gone bad? Has anyone attempted to repair such a thing?

Any help is much appreciated!

Firstly the 2.0 and 2.1 systems you reference are for models 2003 - 2008, your model year got 3.0

I seem to remember the audio interfce being little more than an antenna like analgue one, so the volume on your devices have an impact on sound levels. The fact that the USB digital input works fine tells me that maybe your right the analogue input stage or device is shot or had lost power

Check your fuses
