I say most, because I was told by the vendor upon requesting the device that “Magic Box doesn’t have 100% compatibility with Honda.” That could be a problem since I’m testing with a 2018 Honda CR-V. “But most of the time, it works,” they said. So why not try it?

To stress the point, the DG80 is an audio-only Bluetooth adapter, which means it won’t connect with anything other than headsets, soundbars, or speakers. Specialized support for AptX Low Latency and FastStream work great with compatible devices to keep your audio lag-free and beyond CD quality, making the DG80 a brilliant go-to for wireless audio in the home. On the home screen are apps to launch CarPlay or Android Auto, plus others such as Google Maps. Pretty much any app available in the Google Play store or that you can sideload is an option—they even ship with a few of the non-Google-Play apps available on the device. You’ll need to log into individual apps and keep them up-to-date, like on your phone. If you prefer to mirror your phone to the dashboard (or your TV), you select the Phone Cast app and activate screen mirroring on your phone—it should work like a charm with iOS.WIDE COMPATIBILITY - The C81 adapter is designed to work with a wide range of devices, and makes it simple for previously unsupported devices to now have Bluetooth capability. Easily transmit audio wirelessly from your USB-C ported PS5, Switch, or PC/Laptop to your Bluetooth headphones or speaker. In addition, a converter cable is included to enable devices with just a USB-A port to have the same functionality.

While you’ll find the BTD-400’s operating support fairly extensive, when it comes to consoles, things aren’t so impressive. Unlike other adapters in our selection, the Kinivo won’t work as a Bluetooth adapter to manage your wireless headset for PlayStation, Xbox, or Switch. You can, however, use any Bluetooth-enabled console controller with the BTD-400 if it is connected to a PC or laptop. If you still can't get C81 pair with your bluetooth headphones/speakers, please try to Factory reset C81and your devices and then pair them again as above. Carlinkit’s U2W Plus, sometimes also called the Carlinkit 3.0, is one of the most advertised CarPlay-only dongles out there. The company also sells a combo CarPlay+Android Auto device called the 4.0, and the A2A for Android Auto-only use, among other devices. The 3.0 is rated to work with the iPhone 6 on up running iOS 10 on up, and in any car with factory-wired CarPlay except BMWs. From the Cplay2Air interface on the dash, you can choose between different iPhones if multiple people have them and are all vying for control. Then the screen switches over to CarPlay. Your iPhone treats this as a new instance of CarPlay, so if you have the icons pre-arranged, you’ll have to arrange them again in Settings > General > CarPlay.Ottocast says the U2-Air works with 600+ car models from 2016 on, except for some Sony aftermarket head units. Its boot time is rated at 18 seconds, and it defaults to 5GHz Wi-Fi. This model only works with iPhones running IOS 10 and up. Unlike some of the other vendors in this roundup, Ottocast has actual offices in the US, but that doesn’t mean the device arrives in the mail any faster. One end has a USB-C port, and the other end has a USB-A port—but the latter is only for offline upgrades, so ignore it. The box contains two cables, one C-to-C and another C-to-A; to get started, plug the USB-C end into the Carlinkit 3.0 and the other end into whatever port you have on your dash or head unit. The first CarPlay adapter I tried, the Cplay2Air, is straightforward: You plug the Cplay2Air directly into the car’s USB-A smart port via the integrated cable.
