I bought codes from a Russian hacker, he's gone mainstream now with a website, don't remember how many digits. The screen may or may not change, my unit came from a Boxster and the first time it came on showed one, thereafter it just shows "porsche." I don't know about the Ebay sellers, I got mine a few years ago and the climate has changed since then.

I am about to do this and have all the same fears as Mitch48 did. I need help with purchasing the PCM and the codes on eBay. I platoon having a local stereo place do the install and then off to dealer for the PIWIS bit. One of the eBay dealers seems to suggest that the PCM 3.1 units for Panamera and cayenne will not work on a 2013 Boxster S. Can anyone confirm this?

They are physically different. Suggest you read the posts immediately above...

James: Omg this is not gonna be a cake walk. You must get tired of helping everyone with this, I applaud your generosity with your time. I read your long post and some but not all of this thread, I will be reading it all. You have answered my question about the different PCM units, I feel confident at this point.

My question now is about the need for an aftermarket amp. I have the Bose system with bluetooth phone and satellite radio and the CDR31. Will I need an amp ? I'm thinking no because I have the Bose system. Will the sound likely be good with the stock Bose amps?

Interesting and frustrating about the FM antenna. I saw that Mitch48 said this wan't an issue for him and I use FM only infrequently so I think I might pass on this

Do you have the website for the Russian fellow with the codes?

I’m thinking of doing this upgrade, and this thread has been very helpful. Mitch has also been helpful when I’ve reached out to him personally.
I have 3 dealers within 100 mi of me, I’ve called the biggest one (which does a ton of business, I would imagine it’s one of the bigger Porsche dealers), I spoke to a service advisor on the phone who said they would be unwilling to install the PCM or code...

so my question is, how have you guys gotten the dealer to help out with install or coding?

HI there: I am just starting out on this, doing preliminary research. Were you ever able to find a dealer to code your unit? My sense is that my local dealer doesn't want any part of this. Did you provide codes you purchased from the Russian fellow?

 

[Porschegasm]

Ref your spec. I am UK based and (as far as I know) we never had the option of CDR31 plus Bose. (We did have CDR31 with a separate amp, called Sound Package Plus (SPP), which I think is the base spec in North America). We could also get a version of the PCM that didn't have nav functionality included and that was available with Bose.

So my question is: are you sure you really have CDR31 plus Bose? And that it's not CDR31 plus the SPP amp? Or that it's not a 'PCM3.1 without nav' plus Bose?

James

An excellent point. I haven't received the car yet, I just purchased it and it is being shipped form a Porsche dealer across the country. My avatar is a picture of it. I know it has Bose as I have the build sheet showing option 680. I checked this and it is indeed the Bose Surround Sound option code.

It looks like a CDR. That is, it has no MAP or NAVI buttons on the left side, instead it has CD AUX and SAT. Also there is no central metal slot on the unit that I see on the PCM. (what is this slot by the way?)

I did call a local dealer and asked this question a day or two ago. He looked up my VIN and said he sees "PCM parts" as part of the equipment on the car.

So, if this is indeed a PCM without NAV, why does it look like a CDR31? If it is a PCM, what are the capabilities and the screen resolution? Here are some pics. Thanks!!!

I found the below below photo of the PCM connections that may be helpful finding an eBay unit with the options you are looking for.

Thanks! that is awesome. Do you know the difference between part numbers 991.642.963.00 and 991.642.963.11 ? Both are listed for boxster and Cayman. Both have XM and do not have the built in phone

 

[Porschegasm]

The last two digits are, I believe, similar to a 'version' level. The '11' unit will be newer than the '00' version. Date of manufacture is shown on the small label on the side of the unit. The spec (eg: phone, XM, etc) is shown on the large label on the underside.

James

A question for the gurus: a salvage yard I contacted has a unit but they do not know the VIN of the vehicle it came from. Is this a deal killer? Can’t this information be obtained directly from the unit once it’s hooked up to the PIWIS? Do I need the old VIN to get the codes?

 

[Porschegasm]

I am not sure about if you need the existing VIN to code the PCM but I wouldn't be surprised if you do as i assume the activation code ties the PCM to the VIN to avoid being able to use a stolen unit. As you are searching for a used PCM I would personally be looking for a unit that would have the HW Version 4 which was from a later 2013 or later. This allows you to upgrade the the latest V4.76 software and allows adding some of the lesser expensive back up cameras and also has jukebox and later functions like Email and Text support that the 2012 and early 2013 with HW Version 3 do not have.
Jim

Is there a way to tell what version you have without the unit in hand? Is there something on the label?

 

[Porschegasm]

Well I made a purchase. A Cayman/Boxster/911 unit that looks clean to me with 100 GB HD, siriusXM and bluetooth. Here are the pics:

Ok then, I have digested more of this voluminous thread. I am going to need that second mic and a GPS antenna for my 2013 Boxster S 6mt. I am having trouble with the part numbers. The one John Alpin listed for the mic doesn't seem to spec for the 2013 boxster. I have to say that I am really not good at finding these parts on the internet. None of the usual parts sites seem to list them.
Question: Do I need the Porsche GPS antenna or will an aftermarket job work just as well. This goes behind the rearview mirror, correct? Thaks!

 

[Porschegasm]

Now just waiting for my car to be delivered. The PCM I got off ebay will be here Saturday. I'm thinking that a generic GPS will work just as well as the Porsche one, which along with connecting cable costs $160. Thanks mitch48.

 

[Porschegasm]

That Dmitry is reliable but a man of few words. I have satellite and bluetooth already in the new car with the CDR31. I purchased his codes for NAV and MAP. Do I need new codes for satellite and bluetooth even though I already have these? The forums aren't entirely clear on this point.

 

[Porschegasm]

So I am ready to do the PCM retrofit and I have all the parts I think I need: second mic, aftermarket GPS antenna, USB cable and plastic fitting for it that goes in glove box. My question is, is there a connecting wire for the second mic that I need? If so, does anyone know the part number for this so I can order it? Thanks!!

 

[Porschegasm]

Here is the issue. When I ordered the mic from my dealer’s parts guy, I got this(see pic). There is no connecting wire. He said the “02” part replaced the “01” part.

I was able to only find the entire wiring harness for both mics online, part 991 044 900 37. I ordered that.

i hope it works
