I re-read this thread in its entirety and watched multiple YouTube videos before diving in. Happy to say the install went off without a single issue! I put the module/box in the passenger footwell under the carpet. I zip-tied it to the two extra thick wires under there with the vents of the module facing down so they would actually ventilate and not be mashed against the carpet/padding and possibly overheat the module (there is about a 1/2" void between the module and the body of the car if you place it where I did since the module is resting against the two thick wires, it will make sense to you when you get "in there" and see for yourself).

Can't believe I waited so long to do this mod. It's like I'm driving a new car with the upgrade in the tech....lol

Thanks to everyone who posted their experiences in this thread! It really helped me out A LOT.

If that's the case, be aware that any unit you install that wholly replaces the existing PCM - like the iSudar unit appears to do - will result in lost functionality. There are many things the PCM does beyond telephone support that a replacement unit like the iSudar does not. While the iSudar unit supports CarPlay and apparently has an AM/FM radio built in (according to the iSudar website), it will not support any native Porsche function that's built into the PCM. Sport Chrono functionality is one example. Other things you'll lose include at least Sirius/XM, PCM native maps (which display on the instrument cluster), favorite channels displayed on the instrument cluster for selection via the steering wheel controls, etc. This is why installing an add-on board to an existing PCM is IMO a better way to go - you can add CarPlay without losing any preexisting native PCM functionality.

Besides losing nav maps and music selections from the instrument cluster, if you want to know if you'll lose anything else by ditching the PCM, before you splurge on an iSudar head unit you might want to just pull your PCM out of the dash and disconnect it. Then, start your car and see what you've lost on the cluster or otherwise.

My preference would be to go with iSudar to skip the extra boxes but I want backup camera integration.
