Mr12volt Porsche PCM 3.1 MOST Bus Apple CarPlay & Android Auto Interface

Porsche PCM 3.1 MOST Bus Wireless Apple CarPlay & Android Auto Interface

Model No: P3000-PM31

Upgrade your Porsche's PCM 3.1 system with the Mr12Volt P3000 - PM31 interface and add wireless Apple CarPlay and Android Auto to your vehicle without replacing your factory PCM unit. The Mr12Volt kit connects directly to your Porsche's MOST fibre optic network, the same digital audio path Porsche itself uses, so sound quality, steering wheel controls and PCM touchscreen operation all continue to work exactly as intended. CarPlay Direct is the official UK stockist of Mr12Volt with UK support.

Mr12Volt Porsche PCM 3.1 Key Features

1. Wireless Apple CarPlay and Android Auto: connect your iPhone or Android phone wirelessly, plus a wired option if you prefer a cable.
2. Genuine MOST fibre optic integration: connects to your Porsche's own digital audio network, not an AUX input or a Bluetooth dongle.
3. Retains OEM controls: your factory PCM touchscreen, steering wheel buttons and rotary controls all keep working exactly as before.
4. Siri and Google Assistant: make calls, send messages and control music using your Porsche's factory microphone.
5. Screen mirroring: mirror your phone's display for apps that Apple CarPlay or Android Auto don't cover natively.
6. Bluetooth audio streaming: play music from your phone without a cable.
7. Aftermarket camera support: reversing, front and blind spot cameras up to AHD 1080P.
8. Plug and play installation: no coding required.
   

How the Mr12Volt PCM 3.1 Kit Works

• Selected through the TV source on your Porsche's PCM menu
• If your car has a factory TV tuner module fitted, it must be bypassed to use the kit
• If your car has both a factory TV tuner and a factory reversing camera, contact us before ordering to confirm compatibility
• No coding required
  

Compatible Porsche Models

PCM 3.0 and PCM 3.1 look identical on the dashboard, so a registration year alone isn't proof. With the ignition on, press SOURCE and INFO together on your PCM unit and the screen will show the software version. If it says 3.0, you need our PCM 3.0 kit instead of this one.

Porsche MOST Fibre CarPlay vs AUX Interfaces

Most Porsche CarPlay adapters on the market connect through the AUX input or mirror your phone's screen over HDMI, which compromises sound quality and drops functionality your factory system already gives you. The Mr12Volt P3000-PM31 interface integrates directly with your Porsche's MOST fibre optic network instead, preserving digital audio quality, steering wheel controls and PCM operation exactly as Porsche intended.

I recently purchased a Mr12Volt PCM 3.1 unit from Car Play Direct for my 2014 Porsche Macan, and I couldn’t be happier. Customer service was excellent from start to finish, delivery was impressively fast, and the unit itself feels truly premium. The quality is superb and integrates perfectly with the vehicle—highly recommended for anyone considering this upgrade.
