Pcm replacement question
Quick question: Is it a basic swap and play to replace the PCM/radio unit from another Porsche or is there programming involved?
on a separate question, Has anyone replaced the PCM with an aftermarket touchscreen, has anyone used this kit with an aftermarket head unit to work with the steering wheel controls?

I don’t know how much longer I plan to keep my Panamera but either way I do need to get the PCM working again. I was able to remove the PCM unit and can tell that the HDD is clicking. So that is gone. I was going to try to remove the HDD and see if I could see the contents on my PC.

I got mine from
https://obd2.market
if the HDD not totally gone yet you can clone it on a SSD using a disc clonner double bay. I got it for 30$ from Amazon. Buy if is totally gone I don’t know what you can do. May be ask dealer how much for the pcm software only. Is it a Bose system ?

At least the main question of purchasing a PCM system on eBay would be harder than just a plug and play. I was looking for a PiWiS device but I don’t think I was looking at the right product. I just saw a cable with ODB II PLUG to USB on eBay.

Man I know 20 questions. Just want to make sure I understand what this is and I am biting what I need to make sure if I buy a replacement PCM, I can program it to work in my car.

You just need to replace the HDD in the PCM, clone it and re-install. I've been down this road. My PCM is on version 1.35, so it needs an update. Your PCM can be updated easily, since the ISO available on rennlist. There are a few long threads that will talk about this issue.
I swapped out my HDD and re-installed the unit, and it would still reboot. The issue was XM radio was still trying to update and access their portion of the HDD. Once I canceled XM and it was completely off, the PCM was rock solid.

Good info, and you can have the PCM up and running in short order.

The original HDD in the PCM is bad, or going bad. I don't know what yours is doing. Does the PCM work for about 2 minutes and reboot? If so, you can still remove the PCM, remove the HDD and clone it, and re-install the new cloned HDD. There will still be a bad spot on the new HDD, since you cloned the bad spot onto the new HDD.
Once you install and run the update CD, it will erase and fix the 'bad' spot on the new HDD. You'll then be back to 100%, even with XM working.
Running the update disk without changing the HDD won't do anything. It will try to write to the bad section on the HDD and fail, and crash.
That thread on rennlist is comprehensive and what I used to get my PCM back up and running. Since my PCM version is at 1.35, it makes it a little more difficult, since there aren't a lot of PCM ISO files in the wild.

so my system version 2.47; PCM 3.1. Are there any upgrades? Additional features that can be added? DVD upgrade or mp4 player? Android auto?
