Audi A4 Wireless CarPlay Adapter: Full Setup Guide (2017–2026)
If you drive an Audi A4 and you're still plugging in your iPhone every time you get in — this guide is for you.
The A4 is one of Audi's most popular executive saloons, known for its refined interior, precise handling, and premium MMI infotainment system. Audi added wired CarPlay support starting in 2017, but wireless CarPlay didn't come standard until much later. The good news? You can upgrade any A4 with wired CarPlay to wireless in under 60 seconds — no coding, no dealer visit, no Audi subscription required.
Does the Audi A4 Support CarPlay?
Yes — here's the breakdown by generation:
- B9 (2017–2019): CarPlay available on trims with MMI Navigation Plus (Virtual Cockpit models)
- B9 Facelift (2020–2023): CarPlay standard across most trims with updated MMI Touch system
- B10 (2024–2026): CarPlay standard with the new MMI system across all trims
Quick check: If your A4 has a touchscreen and a USB-A or USB-C port in the center console, you almost certainly have wired CarPlay — and you can go wireless today.
