If I look at the virgin SD card (before putting it into the car) I have the following 3 folders and 1 txt file:

FOLDER: iGO 8/11/2022 11:27 AM
FOLDER: Manuals 8/11/2022 11:39 AM
FOLDER: System Volume Information 8/11/2022 10:29 AM
FILE: devinfo.txt 3/4/2013 6:34 AM

After putting the SD card in the car, some "extra" folders showed up, some with strange names and some curious dates.

FOLDER: Android 12/31/1979 11:00 PM
FOLDER: iGO 4/7/2023 3:01 PM
FOLDER: LOST.DIR 12/31/1979 11:00 PM
FOLDER: Manuals 8/11/2022 11:39 AM
FOLDER: System Volume Information 8/11/2022 10:29 AM
FILE: devinfo.txt 3/4/2013 6:34 AM

I can understand the Android folder showing up as the PCCM+ integrates the map information into the system, but the 1979 dates look like some programmers trick to keep track of something. The LOST.DIR folder, which contains a single file of 32 KB of nulls, looks more problematic.

Since the new card is still defective for anything past New York, the next steps for me will be (1) call Porsche Classic Customer Service and add my troubles to the open case I have. (2) Try the (almost) local Porsche Classic dealer to see if they have any real (from Porsche) information on fixing this. (3) If nothing works, I will probably ask for a refund from the dealer who sold me the SD card, and then wait until the smoke clears and a reliable fix shows up.

For those with the Premium sound system (non-Bose and non base - I think it’s called premium sound system, right?)… when you disconnect the MOST adapter the speakers function properly. With it connected, the speakers were never really all there. Now, I think they are too loud, but the sound is actually fully there, whereas with the MOST connected it’s as if many frequencies were just non-existent. Also volume with the MOST adapter is a problem so I’m now worried about blowing speakers and my eardrums but it sounds better than before.

I figured this out because I was forced to connect the external microphone. My internal no longer works after several “factory resets”. Also went into the developer mic volume menu and it won’t let me adjust the UPLINK internal microphone volume to anything other than 6. I was able to adjust all other numbers. This is regardless of whether or not the MOST adapter is connected. Anybody else having issues like this with the internal microphone? I’d much prefer to go back to that and adjust volume like in the sticky.

And you get a better sound, more active speakers , if you simply disconnect the MOST from PCCM+??

Do you have the ASK most amplifier in the trunk??
behind the tire pump and toolkit?
because normally speakers are wired there

I double checked all the pins and they looked good. The only thing I could determine that changed the sounds was disconnecting the MOST. My speakers were great before the install and I was very disappointed when I installed the PCCM initially.

So when the PO tried to upgrade it to PCM/ASK.. he didn't manage to do it.

To "upgrade a CDR to a PCM with ASK, would require rewiring the entire car speaker system.. to the frunk.., and I don't see anybody doing that makes no sense.
That why you have nothing on MOST, because your PCM at best finds the ASK amp, but there are no speakers wired to it.. at worst, it does not even detect anything on the MOST loop.. if at all the most loop is working and if at all the ASK amp has power .

So they probably just stuck the PCM in there and hooked it up to the existing CDR wiring loom, eg standard speakers without using the ASK amp

And so you have to use those analog wires...

You can probably sell off the most adapter, maybe even the ASK amp (untested)..

Not sure why they bothered installing the PCM to be honest.. without the navi DVD player, the navigation would not work
and without the ASK wiring.. the ASK did not improve the audio quality either..

Basically the PCM only did what the CDR did.. with a bigger screen, that's all it did.


IF you ask me , when this PO sold his car to the next buyer.. the PCM, was a bit fraudulent.. because it was not a properly installed/working PCM at all.

Maybe I'm wrong but it seems like it would be a lot of work to add the ASK amp (including associated trim pieces), wiring and additional speakers after the fact. It's also possible your ASK amp is going bad (as these tend to do) or you have a bad converter box.

Clearly not the case for him. Sincr he has working speakers with most disconnected from pccm.

That means the speakers are wired to the din connectors in the center console.. not in the frunk

I tested to ensure the pins and harnesses were all securely attached and the only difference was when I disconnected or connected the MOST adapter and restarted the PCCM and reset to factory settings. So you think I'm completely bypassing the amp in the frunk and speakers are only powered by the PCCM now?

Thanks in advance.

I’ve had mine installed for a couple months now and it’s been just fine keeping it on and definitely reduces the glare. If you don’t like it you can keep it on until you find a suitable replacement! Plus it doesn’t retain fingerprints as bad as not having one.
