CarPlay and backup camera retrofits for factory head units

A retrofit interface sits between your car's original radio and its own wiring. It adds wireless Apple CarPlay, Android Auto and MirrorLink to the screen the car already has, and feeds a backup or front camera into the same display. Nothing is cut, nothing is coded, and the kit can be unplugged before a lease return.

Audi: three factory radios, three kits

Audi shipped three infotainment families. Concert or Symphony is the base radio — it came bare, with no camera and no CarPlay at all, so a backup camera is part of that build. MMI 3G was the top system until 2016. MIB and MIB II run from 2016 to 2025. One interface per family; the wrong family will not fit.

When you need a camera and when you don't

Many Audi built from 2014 already left the factory with a reverse camera, and the interface works with it as-is. Add our OEM-style camera — built into the trunk handle, with dynamic guidance lines — only if the car has none. On Concert and Symphony cars it is always needed.

Frequently asked

Fitment guides →
How do I know which head unit I have?

The screen size, the controller shape and the software-version screen identify it. Our Audi and BMW guides walk it in about two minutes, or email the VIN and we confirm the kit before you pay.

Do I need a backup camera with a CarPlay kit?

Only if the car has none. Many Audi from 2014 already have one and the interface uses it. Concert and Symphony cars always need one — that radio was sold without a camera.

Will the factory radio and Bluetooth keep working?

Yes. CarPlay is added as an extra source; radio, media, factory Bluetooth, steering-wheel buttons and the factory microphone all keep working.

Is any coding or dealer visit needed?

No. The harness plugs between the head unit and the car's own connector. No coding, no cut wires, fully reversible.
