Full-Screen Android Auto Activation for Porsche – PCM4.1 / PCM5 (HD)

Recognise any of these?

Your Android Auto works but only displays in that small windowed box — you're squinting at a postage stamp while driving.
You bought your 992, Cayenne, Macan, or Panamera used and it didn't come with full-screen CarPlay or Android Auto enabled, even though the hardware is already there.
Your dealer wants hundreds of dollars just to activate a feature that's already built into your PCM — and told you to book it in for a half-day visit.
A mate with a newer or higher-spec Porsche gets full-screen navigation and yours sits in a corner of the display looking like an afterthought.
You've updated your PCM firmware and still can't figure out why Android Auto won't go full screen, no matter what you try in the settings.
