Isudar Carplay for PCM 3.1

I am in a 958.1 2014 Porsche Cayenne. I am pretty certain was version 2.0.0b. Firmware is unknown. I installed it around March 2022. Basically when the car is turned off, for example when you are parked, and you don’t open the door all interior electronics stay on. (Until the door is opened). This includes the PCM display. I was waiting at the airport with the car parked and not running. The display remained on and was working perfectly fine and then turned black. Now it refuses to display anything while the car is running, even the OEM pcm 3.1 OS. It has been almost a week. I am trying to find a way to contact ISUDAR at the moment as well.
As for contacting Isudar I found the best/fastest way was through WhatsApp, they usually reply overnight on week days.

I am growing quite frustrated and wondering if anyone else has experienced something similar. I have been using my ISUDAR board for years now. I keep running into an issue where if the car is off, the panel stays on and connected until I open the door. It eventually turns off and goes black. That would be fine if it behaved properly. Whenever this occurs my PCM 3.1 will not display anything for a while. Usually this would be fixed after letting the car sit overnight, and starting in the morning. This time the PCM will not turn on no matter what. I made sure my phone is disconnected and have forced a reset multiple times by holding INFO. I can hear the system turn off and on but no image will come up whatsoever. Has anyone run into this? Any help would be appreciated.
Usually, if the unit is powering up but the screen is black, it indicates that the ribbon display for the screen is not properly connected. I wonder if yours has vibrated itself loose over the years you have the board installed? Might be worth opening up the PCM and reseating the ribbon cables?

Hey guys, quick question. I have just received the Isudar PCB. Is it still the case that you must install an external microphone in order to use Siri? Or can Siri nowaydays be used over the stock Porsche microphone as well. According to the manual you still need an external mic but I seem to be reading something different here in this thread. Thanks!

You can look at the PCB they sent you. It should say on it which hardware version it is in the silkscreen.
I have the same setup as you and I ended up removing the green shroud off the sirius XM module connector which won me about 2-3mm of space and allowed the board to clear with the two stacked spacers. I also wrapped some electrical tape over the (now bare) connector, just in case the board rubs a bit to keep it from wearing through the solder mask on the PCB and causing shorts.
Note: earlier they were shipping the wrong size spacers, so if you bought this a while ago like you said, you may need to email them to ask for the taller spacers.

Hi,
Is this the one you removed to get more clearance? does it come off easy?
Thanks for the help.

Removing the plastic around the connector is one way to go. Alternatively, at least in my case, using the studs included in the Isudar kit with a bit of adjustment allows you to install the Isudar board without modifying the plug. You need to combine one long and one short stud. Then, do not fully screw the studs together to make the total length of the combined studs a little bit longer. This allows for enough clearance between the Isudar board and the plug while also been able to reassemble the PCM without damaging the cables.

These issues have been discussed many times in the the thread, with various good solutions proposed. Here's one:

It was about setting the board at a height that cleared the XM connector and did not interfere with the underside of the CD/DVD player.

Try this extensive thread for details of various different had units which will work with your car:

I have personally used in my Panamera the wide-screen unit linked here:

I have also used this unit in my wife's Cayman:

A similar version of the above is available also for the Panamera. If you search on Ali Express, you will find several variants. I have had both of these units in our cars for some months now, with no significant issues or problems.
There are no issues such as those you describe. All of the OEM controls from the PCM are available in the new HUs, which have specific canbus modules for each model. Door locking, lights controls, reverse camera, radar parking sensors, etc etc are all retained. Personally, I favor the aftermarket units since they feature much better screens with way higher resolution, plus the ability to run any one of the thousands of Android apps in the Google Play Store, as well as wireless Android Auto or Apple Carplay.

i know this question doesnt really belong here but i need help..
i installed aftermarket android headunit on my 970.2. It has burmester speakers. I am having an issue when the android headunit turns off, a second or two later loud popping noise comes from the cabin. I tried ground isolator and low high impedance converter. None of them works. What I found from the web is it could be that the amp is turning off too late compared to headunit.
the diagram above shows there is “amp on” pin there. Is that also the same pin used for amp off? Can i just connect that line from the harness to android headunit harness accessary line?
Thanks for your help!
