Hi I got my CHSTEK model installed in car toys. The installer said he connected the aftermarket backup camera to the model, but it is still black screen on it. He believed the wire setting is correct. He said what he used to do for other unit is to do some setting in the system to make the after market camera replace the original camera from factory(which my car does not have). But he could not figure out how to set it for this unit.
I tried to contact the seller on Aliexpress but got no response.
Any suggestion for it? Thanks!

This was my biggest concern when swapping out the PCM, but after thoroughly looking into it, I didn't really have anything to be concerned about. Sport Chrono still functions as normal through the instrument cluster display, you just lose the functions of it only accessible through the PCM, which isn't much. Also, as Andy said, no nav or audio information will be available in the cluster display, but those maps are dated anyway. That's pretty much it. There can't be much locked behind the PCM because Porsche sold cars with just a shelf in the head unit spot if you wanted. All the needed controls are available in the instrument cluster display, and the aftermarket head units can also control vehicle functions via CANBUS.

I don't have steering wheel controls, but they do still work with aftermarket headunits as far as I know. My Chstek unit has a menu for programming them. To be honest I forgot about the phone menu in the cluster because I didn't use it, but yes, that would also be gone. The headunit comes with its own mic.

Thanks for confirming. That's a bummer, but I guess it's fine if you don't use the phone in the car often. AFAIK, most of these external mic is terrible compared to the built-in mic. At least the steering buttons still works which is really great though I have none on mine for now.

You can buy a good mic for not much money and plug into the back of the HU. My Panamera unit gives me the option to use the OEM mic, but the unit in the Cayman doesn't so I installed an external mic. I located it on top of the driver side A pillar, with no visible wires. It looks pretty neat but you have to look closely to even notice it. Steering wheel buttons, if fitted to the car, still work as usual - you just have to program them one at a time in the relevant settings page. After that they all work as before.

It definitely does. What makes you think it doesn't? How are you trying to set it up? What phone are you using? I assume you have been able to set up AA using a USB cable? Is BT turned on on your phone and on the HU? Do you have Zlink on your HU?
