How It Works

Setting this device up couldn’t be easier. It is just a matter of plugging it into the USB on your head unit and turning the device on in your Bluetooth settings.

OttoCast U2 Now Review

This is another of the most popular brands out there. OttoCast makes a variety of different wireless adapters to connect with wired head units. This is the newest design for 2021 and it improves on other designs by incorporating 5g technology for faster processing speeds. It works for most factory head units featuring wired CarPlay built after 2016. While it isn’t intended to work with aftermarket systems, it has worked on several models of Sony head units.

Faster processing speeds make this adapter one of the fastest to connect to your phone. The manufacturer claims times of less than 30 seconds, but owners say the device is usually connected within 10 seconds of starting the car.

How It Works

Like most similar devices, this integration solution connects to the USB input on your head unit. It only works with Apple iOS 10+ and won’t work with some vehicles. The device allows for full retention of factory steering wheel controls without the need for adapters or other additional parts. The 5gHz Bluetooth connection provides very low lag, even when using Apple Maps.

Pros
  • Simple and basic device that works better than expected
  • Quick startup time with limited lag
Cons
  • Does not support screen mirroring
  • Noticeable delay when taking hands-free calls

Drimfly AirCarPlayQ Review

This is an excellent solution to wirelessly accessing the features of your built-in wired CarPlay functions. The dongle is simple to conceal and has an attractive high-end look and feel. An illuminated LED lets you know that it is functioning correctly.

It connects with virtually any iPhone you’ll find, from the iPhone 5 up to the latest iPhone 13 pro Max. The manufacturer claims connection times of four to seven seconds on average.

How it Works

The secret to this solution is the use of both Bluetooth and Wi-Fi to establish a connection. The dongle first establishes a temporary BT connection with your phone, then switches to a Wi-Fi connection to get you on the road hands-free quickly. Coupled with 5G connections, this option offers one of the fastest and most stable connections.

Pros
  • Connects quickly and has no lag on navigation screens
  • Attractive appearance with indicator light
Cons
  • Some occasional delay present when using touchscreen features

OttoCast U2X Review

So far, all of the products we’ve shown you work for either Apple CarPlay or Android Auto, which is fine if you only use one or the other.

That’s where this handy dongle from OttoCast comes in. It supports both Apple CarPlay and Android Auto to convert wired connections instantly to wireless.

It works for iOS10 and Android 11 or above systems and allows you to use either Siri or Assistant while making it convenient to use your favorite maps, navigation programs, or access your favorite streaming services handsfree.

How it Works

The U2X comes with USB-A to USB-C and USB-C to USB-C cables to allow compatibility. Built-in 2.4ghz Wi-Fi allows the dongle to connect your smartphone with your wired head unit.

Pros

Motorola MA1 Review

This is one of the newest designs on the market, and at the time of this writing, it’s a little difficult to find. That makes sense, since it has some of the highest specs you’ll see, including 5ghz Wi-Fi connections to ensure high-speed data transfer wirelessly. This is a discrete dongle that easily is hidden from view and provides simple wireless Android Auto performance.

How it Works

One of the things that sets the performance of this device past others is the licensed use of Google technology that allows for a seamless pairing with native Android systems. The high-speed connection enhances navigation and music playback performance.

Pros
  • Easily concealed small design
  • Excellent connection quality
Cons
  • Relatively new to the market so there aren't too many consumer reviews

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.

We got the opportunity to test the Carsifi out first hand. If you're interested in reading more about our experience with it, check out our Carsifi Installation & Review.

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.

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

Things to Consider about Wireless CarPlay and Android Auto Adapters

There are a few things you’ll want to consider when you’re looking at these types of adapters. Most importantly is compatibility. Be sure to check that your vehicle is compatible with the adapter you’re considering. Not all vehicles are compatible with every adapter. Secondly is delay. We’ve seen and heard of significant delays with some of the knock off adapters so finding one that’s high quality and limits the delayed responses is important for a good experience.

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.

Conclusion

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.
