PCCM+ install woes--NO SOUND

Need for PCCM instructions from Porsche
I've been following all the drama related to the PCCM+ installation woes in the multiple related threads. I understand that Porsche wants this installed via the Dealer but it seems that even the dealer instructions are inadequate to address the various installation issues noted in the threads. You'd think there would be a more comprehensive installation procedure with Porsche documented instructions for these units and not leave it up to the forums to resolve issues that should have not have been issues to begin with.

No grounding issues on MOST cars. Make sure all connectors are plugged in. (I am sure you probably did this already) Maybe you have a defective unit.

As it stands right now, the consensus is the PCCM+ does not offer pre-amp analog line-level output via the C1 ISO output. Therefore, the SPEAKER LEVEL output from the B connector on the PCCM+ will have to be attenuated to LINE LEVEL to avoid distortion with the M490 HAES amplifiers. This is for non-MOST analog systems from 99-2002. Bergvill has been producing radio solutions for Porsche for many years.
Here is a Hi/LO adapter/ wire harness for this solution.

man. What a drag. I think my dealer/repair place is going to try and help me out. He did advise me to try and turn off the radio, get out, lock and unlock the doors, and then try starting the unit again, but that didn’t work. Funny story – this is actually voice to text dictation coming through the microphone on the unit.

Did you check for sound before switching from CAN to AMP? I thought that was only for earlier models.

Just as a follow up here. I reached out to Sunset Porsche where I ordered my PCCM+. They told me they heard from Porsche who has acknowledged the amplifier issue with the analog cars, but do not yet have an official fix. I went ahead and ordered the Bergvill adapter above to see if it would fix my install. Will report back once it comes from Norway or wherever it ships from.

Yet another situation where actual directions would have helped...
Aside from this tomfoolery, this install was actually quite easy!

To add an additional wrench in this conundrum, I received the BergvillFX adapter that was recommended here for analog cars. Plugged things in and no sound. The adapter had what seemed to be like an extra brown plug. After looking around I've now realized that there are two different analog sound systems with amps. Some cars got a Hayes amp, but my car has a Bose amp. Not to be confused with the digital Bose system? So now I'm going to try this harness from BergvillFX to see if it will work? https://www.bergvillfx.com/products/...96boxster-bose

Has anyone found a wiring diagram for the PCCM+ ? I am in communication with the Bergvill F/X team regarding a harness that might fix the gain issue, but they cannot commit to anything without knowing for sure what the pinout is for the PCCM+.
