With these screens comes new distractions while driving and the potential for serious danger on the road. Solutions for distracted driving like Apple CarPlay and Android Auto head units have helped to integrate our connected devices into our intelligent cars, but the corded connection is often a nuisance or a distraction. With corded connections, every time you would like to use CarPlay or Android Auto, you have to pull your phone out of your bag or your pocket and physically connect it to your head unit or car.

Although wireless adapters for Android Auto are not very common right now, they’re becoming increasingly popular. In fact, the two best products on the market are crowd-funded and in their infancy at the time of writing this article. One product won’t even begin shipping until November 2021. And while there are products around that claim to work, most don’t.

The dongle from AAWireless has been on the market for about a year. In that time, it has undergone constant real-world testing and improvement. The current version that will be shipping later this year or early next year promise to be the best versions of an already above-average product.

This is a simple fix for wired Android Auto environments that works on thousands of cars and dozens of brands. It even works on some aftermarket head units. It doesn’t require an app, there aren’t any crazy settings, and it works right out of the box. Plug it into the head unit, connect via Bluetooth, and follow the prompts. You’ll be wireless in no time.

How It Works

The dongle plugs into the USB-A port on your head unit. When the Bluetooth connection is established, the dongle will communicate with the head unit and your phone, connecting your Android Auto app to the screen with full functionality of factory controls.

As a crowd-funded start-up with only a year or so on the market, there have been issues with connectivity along with various other issues and feedback that have been given to the company to improve their product. The company has built a reputation so far on transparency and attention to customer feedback. Upgrades to the device have been frequent and have addressed numerous issues.

Carsifi Review

This is another crowd-funded design that hit markets in November 2021. This device is similar in many ways to the AAWireless design. It uses a different processor that allows the dongle to connect wirelessly between two devices so you can switch back and forth.

This dongle works with hundreds of brands of cars and aftermarket head units. The dongle does not require the use of an app; however one is available to give you access to settings and additional features.

How It Works

You’ll need a factory or aftermarket head unit that has Android Auto built in. Connections are as simple as plugging in the USB-A to the head unit and connecting the device through Bluetooth. Once connected, you won’t need to plug your phone in again.

Since this one hasn’t gotten into very many hands yet, it’s hard to say if it’s better than the AAWireless device. The ability to simultaneously connect devices makes for something a little different that some people may like.

  • Allows for two phones to connect at once
  • Provides an easy way to get Android Auto wirelessly
  • Easy to connect and use
  • Not yet widely available at the time of this review
  • Will likely require firmware updates after release to address bugs

Why Would You Want a Wireless Adapter?

Wireless CarPlay and Android Auto adapters accomplish one, basic feat: they eliminate the need to plug your phone in to access the features or CarPlay and Android Auto. For some people this isn’t a big deal, but for others the convenience is a game changer. Going fully wireless allows you to keep your phone away so that you aren’t compelled to check it every few seconds. A wireless connection provides a seamless experience that lets you simply jump in the car and go with the features you want coming to life automatically.

Drawbacks of a Wireless Adapter

There are a few drawbacks inherent to most wireless adapters. First, they tend to introduce a bit of lag as the wireless signal is converted to a wired signal. This is often noticeable when running data-heavy apps like Maps and may also show up when streaming music. Particularly slow connections can be due to poor internet or outdated/old devices which can cause the device to fail to connect or have a slow rate of transfer.

Finding a place to put the adapter can also be problematic. Most of these devices include a short USB cable that doesn’t give you more than a few inches of movement. Longer cables can cause slower connections, even when using cables rated for fast data transfer. Users of head units with rear USB ports will have a better time making these devices discrete, otherwise they can be a target for thieves.

Another interesting point – all the adapters on the market at the time of writing this article can connect with only one phone at a time. If you want to have two phones connected and both phones are in the car, the phone that is not connected will need to be set in airplane mode for the other phone to be recognized.

And it's worth pointing out here as well that if you want to charge your phone, you will still need to plug it in via USB unless you have a wireless charger in your vehicle.


Adding Android Auto or CarPlay through a wireless connection is a great way to streamline the interior of your car, reduce distractions, and provide a better-connected environment. These adapters make it so you don’t have to plug your phone in each time you get in and they let you keep your phone put away, so you aren’t looking at it instead of the road.

An Apple CarPlay or Android Auto wired-to-wireless adapter can give you the convenience you want without having to upgrade your car stereo or buy a new car. We did the research on these products to help you find the best option for your vehicle. Hopefully we were able to narrow your search and provide some good insight to help you find the ideal adapter.
