Can You Get Wireless CarPlay on an Audi A3?
Yes — if your Audi A3 came with wired CarPlay from the factory, you can upgrade it to wireless CarPlay using a plug-and-play adapter. No rewiring, no dealer visit, no head unit replacement. The Homniva Wireless CarPlay Adapter connects to your car's USB port and converts your existing wired CarPlay connection into a fully wireless one in minutes.
This guide covers every Audi A3 generation from 2019 to 2026, including the 8Y generation, Sportback, Saloon, and S3/RS3 variants — across the US, UK, Canada, Australia, and Europe.
Which Audi A3 Models Support CarPlay?
Audi began offering CarPlay on the A3 from around 2016, but wireless CarPlay natively only arrived with the 8Y generation (2020 onwards) on higher trim levels. Here's a quick breakdown:
- 2019 Audi A3 (8V facelift): Wired CarPlay available on models with the MMI Navigation Plus system. Wireless CarPlay not supported natively — adapter required.
- 2020–2026 Audi A3 (8Y generation): Wired CarPlay standard on most trims. Some higher trims include native wireless CarPlay, but many do not — check your MMI system version.
- S3 and RS3 (2021–2026): Same MMI system as the standard A3 8Y — wired CarPlay standard, wireless via adapter on most builds.
If your A3 has a USB-A or USB-C port in the centre console and CarPlay works when plugged in, the Homniva adapter will work.
What You'll Need
- Audi A3 with factory wired CarPlay (2019–2026)
- Homniva Wireless CarPlay Adapter
- iPhone running iOS 10 or later (iPhone 5 or newer)
- Bluetooth and Wi-Fi enabled on your iPhone
How to Set Up Wireless CarPlay on Your Audi A3
- Plug in the adapter: Insert the Homniva adapter into your Audi A3's USB port (the one you normally use for CarPlay).
- Start your car: Turn on the ignition and wait for the MMI system to boot fully.
- First-time pairing: On your iPhone, go to Settings → General → CarPlay and select the Homniva adapter from the available devices. This pairs via Bluetooth.
- CarPlay launches wirelessly: Once paired, CarPlay will appear on your Audi's MMI screen automatically — no cable needed.
- Every subsequent drive: As long as Bluetooth is on and your phone is in range, CarPlay connects automatically when you start the car.
Does It Work with the Audi MMI System?
Yes. The Homniva adapter is fully compatible with Audi's MMI Navigation Plus and MMI Touch systems used across the A3 range. It works at the USB level — the car sees it as a standard CarPlay connection, so all MMI controls, steering wheel buttons, and voice commands continue to work exactly as expected.
Audi A3 USB Port: What to Know
The 2019 Audi A3 (8V) uses a USB-A port in the centre console armrest. The 2020–2026 A3 (8Y) uses USB-C ports. The Homniva adapter is compatible with both — it comes with the appropriate connector for your port type. If you're unsure, check your centre console or glove box for the port type before ordering.
Will It Affect My Audi's Warranty?
No. The Homniva adapter is a plug-and-play device — it doesn't modify any software or hardware in your vehicle. It simply uses the existing CarPlay USB connection. Plugging in an external USB device does not void your Audi warranty in the US, UK, Canada, Australia, or Europe.
Common Questions
Does wireless CarPlay work on all Audi A3 trims?
It works on any A3 trim that supports wired CarPlay. If CarPlay works with a cable, the adapter will make it wireless. Entry-level trims without CarPlay cannot be upgraded this way.
Does it drain the car battery?
The adapter draws minimal power — similar to a USB phone charger on standby. It only operates when the ignition is on, so it won't drain your battery when the car is parked. For more detail, see our guide on Does Wireless CarPlay Drain Your Car Battery?
Can I use two phones with the adapter?
You can pair multiple phones, but only one can use CarPlay at a time. Switching between phones is straightforward — see our full guide on Can You Use Two Phones on Wireless CarPlay?
Does wireless CarPlay work in tunnels or underground car parks?
Yes — wireless CarPlay uses Bluetooth and Wi-Fi between your phone and the adapter, not a mobile data connection. It works anywhere your phone and adapter can communicate, regardless of mobile signal. Read more in Does Wireless CarPlay Work in Tunnels?
Will it slow down my phone?
No noticeable impact. CarPlay offloads most processing to the car's head unit display. See Does Wireless CarPlay Slow Down Your Phone? for the full breakdown.
