Full-Screen HD CarPlay for Porsche Panamera (971) PCM4.1 – Native HD

Recognise any of these?

You bought your Panamera used and the previous owner never added CarPlay — now you're stuck using Bluetooth audio and typing addresses into the PCM like it's 2012.
Your dealer quoted north of $1,500 to retrofit Apple CarPlay, and that was before labour.
You plug your iPhone in and nothing happens — just charging, no CarPlay, because Porsche locked it out on your build year.
The PCM screen is sitting there at full size but CarPlay is crammed into a small window with a dead grey border around it.
Your passenger pulled up Google Maps on their phone to navigate because the built-in maps are out of date and you can't update them without a dealer visit.
A friend with a 2020 Panamera has full-screen CarPlay as standard and you're driving the same car for all practical purposes — just without it.
