Description

A factory head unit is a closed system. It works on the day the car is delivered and then slowly stops keeping up, not because the hardware failed but because the maps, the apps, and the voice assistant moved to the phone in your pocket. The Interposer exists to close that gap without replacing anything Porsche built.

The module sits between the PCM 3.1 and the screen you already know. It carries wireless Apple CarPlay, wireless Android Auto, AirPlay mirroring, and USB phone mirroring, then hands the picture back to the factory display with the original menu structure intact. Wiring is plug and play on the car's own harness, so the dashboard trim comes off once and goes back on once, with no cutting and nothing to break. The kit ships complete: the module board, a WiFi antenna, power and data lines, a USB line, a microphone, and the two flat flex cables the PCM needs.

Because the install is reversible, the car keeps its value and the original system keeps working. Switch to the module when you want navigation and messages on the screen, switch back when you do not. Nothing about the Porsche interior changes except what the display can do.

The car is finished. The screen did not have to be.

Where It Belongs

Owners of a 911, Cayenne, Macan, Panamera, or Boxster running PCM 3.1 who want modern navigation and messaging without pulling the factory head unit; shops that install electronics for Porsche owners and would rather bill one reversible job than a full stereo retrofit; anyone who wants to keep the car original for resale while still using CarPlay every morning.

Frequently Asked Questions

Q: Does this replace my factory screen?

No. The module feeds the display that is already in the car and keeps the factory menu system. It adds CarPlay and Android Auto as an additional layer, so the original functions stay reachable.

Q: Will installing it damage the wiring?

The kit connects to the car's existing harness with plug and play connectors. No wires are cut, which means the module can be removed and the car left exactly as it was.

Q: Which Porsche models does it fit?

It is built for the PCM 3.1 generation, seen in the Cayenne, Macan, 911, Panamera, and Boxster. Confirm the head unit version on the screen before ordering, because later PCM generations use a different connector.

Q: Is the connection wireless or wired?

Apple CarPlay and Android Auto both run wirelessly. A USB line is included for Android mirroring and for charging during long drives.

Q: What is in the box?

One module board, one WiFi antenna, one power line, two data lines, one USB line, one microphone, and two flat flex cables for the PCM connection.

Q: Does the audio still go through the factory amplifier?

Yes. The module sits in the signal path rather than replacing the amplifier, so the factory speaker tuning and volume behavior stay as they were.

Q: Can I install it myself?

Owners with trim removal tools and basic patience handle it in an afternoon. The dash panel has to come out, so a shop install is a reasonable choice if you would rather not open the console.

The EastSupplier Promise

EastSupplier publishes the head unit generation this module was built for, because the wrong PCM version is the only real failure mode here. Check your screen before ordering. If the fitment does not match what this page says, return it in original condition and the supplier takes it back.

Sound stays on the factory amplifier

No hiss, no channel drop. Android Auto and CarPlay both select cleanly when two phones are in the car.

Factory microphone and wheel buttons still work

That was the part I doubted. Steering controls and the stock mic both behave normally.

Install took an hour in a 911

Trim panels needed to come out and the loom routing took patience. Wireless pairing takes about ten seconds once done.

PCM 3.1 finally runs CarPlay

Plugs in behind the head unit and keeps the factory look. No dash surgery, no phone mount stuck to the windscreen.
