PCM6 Head-Unit Conversion for Porsche – Upgrade from PCM4 / 4.1 / 5

Recognise any of these?

You bought your Porsche with PCM4 or PCM5 and now you're stuck with an interface that feels ten years behind every other car in your garage.
Your dealer quoted you close to what you paid for the car just to get a head unit that actually works the way you want it to.
Apple CarPlay or Android Auto works fine in your friend's newer 911 — yours just has a USB port that does nothing useful.
You're tired of wrestling with the old PCM menu system every time you want to change something simple, like nav settings or audio source.
You've looked at DIY retrofit kits online and have no idea if the unit will actually talk to your car's existing modules without breaking something.
You want the upgrade done properly — with the right coding so everything from the reversing camera to the climate display still works — not just a head unit dropped in and fingers crossed.
