The Mercedes-Benz GLC is one of Europe's most popular premium SUVs — and if yours came with wired CarPlay, you already know the frustration of plugging in your iPhone every single time you get in the car. The good news? You can go completely wireless in under five minutes, with no dealer visit, no subscription, and no permanent modifications.
This guide covers everything you need to know about adding a wireless CarPlay adapter to your Mercedes-Benz GLC, whether you're driving in the United States, United Kingdom, Canada, Australia, or anywhere across Europe.
Does the Mercedes-Benz GLC Support Wireless CarPlay?
Most Mercedes-Benz GLC models from 2019 onwards came equipped with wired Apple CarPlay as standard or as part of an optional package. However, Mercedes did not enable native wireless CarPlay on the GLC until the 2023 facelift (W254 generation). If you're driving a 2019–2022 GLC (W253), your car almost certainly requires a USB cable to use CarPlay.
That's exactly where a wireless CarPlay adapter comes in. It plugs into your car's USB port and converts your existing wired CarPlay system into a fully wireless one — no software updates, no dealer coding, no subscriptions required.
Which Mercedes-Benz GLC Models Are Compatible?
The Homniva Wireless CarPlay Adapter is compatible with the following GLC variants:
- Mercedes-Benz GLC (W253) 2019–2022 — GLC 200, GLC 220d, GLC 300, GLC 300d, GLC 300e (plug-in hybrid), GLC 350e, GLC 400d, GLC 63 AMG, GLC 63 S AMG
- Mercedes-Benz GLC Coupé (C253) 2019–2022 — all engine variants with factory wired CarPlay
- Mercedes-Benz GLC (W254) 2023–2026 — if your model still uses a USB connection for CarPlay rather than native wireless
Requirement: Your GLC must have factory-fitted wired Apple CarPlay. If your car did not come with CarPlay from the factory, a wireless adapter will not add CarPlay functionality.
Not sure if your GLC has wired CarPlay? Check your infotainment system settings under Settings → System → Apple CarPlay, or look for a CarPlay icon when you plug in your iPhone via USB.
What You'll Need
- A Mercedes-Benz GLC with factory wired Apple CarPlay
- An iPhone running iOS 10 or later (iPhone 5 or newer)
- The Homniva Wireless CarPlay Adapter
- Bluetooth and Wi-Fi enabled on your iPhone
How to Set Up Wireless CarPlay on Your Mercedes-Benz GLC
Setup takes less than five minutes and only needs to be done once. After the initial pairing, your iPhone will connect automatically every time you start the car.
- Plug in the adapter. Insert the Homniva adapter into the USB-A port in your GLC's centre console — the same port you normally use for wired CarPlay. Do not use a USB-C charging port.
- Wait for the adapter to boot. The LED indicator will light up. This takes approximately 10–15 seconds.
- Enable Bluetooth on your iPhone. Go to Settings → Bluetooth and make sure it is turned on.
- Pair via Bluetooth. On your iPhone, look for a device named Homniva (or similar) in the Bluetooth list and tap to connect.
- CarPlay launches wirelessly. Your GLC's MBUX infotainment screen will automatically switch to CarPlay. From this point on, your iPhone connects automatically whenever you start the car and Bluetooth is enabled.

Mercedes-Benz GLC MBUX Compatibility Notes
The GLC uses Mercedes' MBUX (Mercedes-Benz User Experience) infotainment system. Here are a few things to keep in mind:
- MBUX 1 (W253 facelift, 2019–2022): Fully compatible with wireless CarPlay adapters. The system recognises the adapter as a standard CarPlay USB connection and hands off to wireless seamlessly.
- MBUX 2 (W254, 2023–2026): Compatible if your car uses wired CarPlay. Some 2023+ models with native wireless CarPlay built in will not need an adapter.
- USB port type: Use the USB-A port, not USB-C. Most GLC models have both — the adapter requires USB-A.
Does It Affect the MBUX System or Void My Warranty?
No. The Homniva adapter is a plug-and-play device that does not modify your car's software, firmware, or hardware in any way. It simply acts as a bridge between your iPhone and the factory CarPlay system. Removing it leaves your car exactly as it was. It will not void your Mercedes-Benz warranty.
Wireless CarPlay on the GLC: What Works and What Doesn't
Once connected wirelessly, everything you'd expect from CarPlay works exactly as it does with a cable:
- ✅ Apple Maps, Google Maps, and Waze navigation
- ✅ Spotify, Apple Music, Amazon Music, and podcast apps
- ✅ Siri voice control (hands-free)
- ✅ WhatsApp, Messages, and phone calls
- ✅ Real-time traffic and lane guidance
The only limitation is that wireless CarPlay does not charge your iPhone. If you want to charge while driving, simply use a separate USB cable or wireless charger — the adapter occupies the CarPlay USB port, so use your GLC's second USB port or a 12V socket charger for power.
