Wireless Android Auto provides a convenient and safe way to access and control your smartphone while driving without having to fiddle with cables or take your eyes off the road. Unfortunately, Not all cars have the necessary hardware and software to support wireless Android Auto. Sometimes, you may need to connect your phone to your car’s infotainment system using a USB cable to use Android Auto.
Even though your car supports Wired Android Auto and Wi-Fi connectivity, you cannot enable Wireless Android Auto due to the lack of hardware support. In such cases, you can purchase a third-party adapter that enables wireless Android Auto connectivity in your car and allows you to use Android Auto wirelessly without needing a USB cable. Once connected, you can use various features such as Google Maps, Google Assistant, Spotify, Pandora, YouTube Music, etc., and make and receive calls and texts hands-free.
Several wireless Android Auto adapters are available on the market from various manufacturers, most of which are designed for easy DIY installation. Ottocast A2Air is one of the most popular wireless Android adapters which can be plugged into your car’s USB port to enable wireless Android Auto connectivity. The adapter pairs with your car’s Bluetooth and connects your phone to your car’s head unit wireless by creating a Wi-Fi hotspot.
One of the best things about Ottocast A2Air is you do not need to remove the phone from your pocket. As soon as you enter the car and start the engine, your phone automatically connects to the wireless adapter and starts Android Auto in less than ten seconds. I have been using this device for the past two weeks, and here is my detailed review.

Ottocast A2Air Design
The Ottocast A2Air has a simple yet elegant design and weighs about 28 grams. The device is fully wrapped with high-quality plastic and has a diamond-pattern design that gives it a premium look and feel. Although the material quality is good, it scratches easily. It’s recommended to keep it in a small case or pouch. The top right end has a LED indicator that tells you the device’s status.
On the bottom, you’ll find a USB-C port to connect the device to your car and a Reset button to flash the firmware using a PC. Note that this is not a Factory reset button but helps you switch the device into Dubug mode while manually updating the device’s software using a PC. The factory reset procedure is different and has been covered in the later part of the review.
Ottocast A2Air Setup
Before initiating the setup, ensure your smartphone has the latest version of Android Auto installed. Check this link to update the app via Google Play Store if available. The Android Auto app automatically detects if your car supports Wired or Wireless Android Auto, so there is no need to enable any other options in Settings. Once you update the Android Auto app, you’re good to go.
One more important thing you should remember is the USB Cable. Make sure you use the cable that comes bundled with the device or purchase high-quality cables from trusted OEMs. Google recommends using a cable under 3 feet (1 meter) long. Also, don’t use USB hubs or cable extensions. You can also try the USB cable that came with your phone. The bundled cables have a length of 30cm and should be enough to keep the device around the USB port or infotainment system. Let’s begin the setup.
Connect the adapter to the USB port of your car. If your car has multiple USB ports, make sure you have connected the A2Air adapter to the USB port to which Android Auto is enabled. In the below image, the USB port on the left is for Android Auto, and the USB port on the right is for charging.
Now connect your smartphone to your car’s Bluetooth. Once connected, Go to Bluetooth Setting, look for AUTO-XXXX (Ex: AUTO-31EB), and tap on it. Allow access to contacts and call log and tap on Pair. In the below screenshot, MG ISMART8 is my car’s Bluetooth and AUTO-31EB Ottocast A2Air adapter’s ID.
Once you tap on Pair, the adapter automatically creates a wireless connection between your phone and the infotainment system. That’s it. The setup is complete, and you can now use Android Auto wirelessly on your car.
Once you Pair the A2Air adapter via Bluetooth, your phone automatically connects to the Adapters Wi-Fi network (AUTO-XXXX). Do not disconnect the device from the Wi-Fi or turn off your phone’s Wi-Fi, or else it will break the connectivity and Android Auto stops working.
I have been using the Ottocast A2Air in my car for over two weeks and am extremely happy with the performance. It simply works without any manual intervention. The moment you start the car, it connects to the phone in less than 10 seconds, even if the phone screen is locked. We just need to make sure the Bluetooth/Wi-FI of the phone is On.
The Ottocast A2Air is a small and lightweight adapter that can be easily kept near the head unit or USB port. The adapter is compatible with a wide range of vehicles worldwide except for a few models such as Skoda, BMW, Mitsubishi, etc. Furthermore, the adapter can be quickly paired with Android phones with Android 11 or later without additional software or drivers.
I have tested the Ottocast A2Air with OnePlus Nord, OnePus Nord 2T, OPPO F21 Pro and Google Pixel 7 and have not experienced any latency or touch response issues. The audio quality has been excellent, with virtually no issues. The phone calls are quick and clear too. I could even use apps like Maps, Spotify, Amazon Music, and WhatApp and talk to Google Assistant without any issues. Also, I did not observe delays while zooming in and out in Google Maps.
The major drawback of the Ottocast A2Air is the lack of a companion app. You need to connect the adapter via an IP address using Wi-Fi Direct to perform specific tasks such as updating firmware, factory resetting, or reporting any compatibility issues. Also, you cannot seamlessly switch between two devices. If you want to connect a second device to the A2Air adapter, you need to unpair the earlier connected device and pair a new device to the adapter, which is time-consuming. Ottocast may introduce an app in the coming months, but the absence of an app is not a deal breaker.
The biggest advantage of this Ottocast A2Air is zero settings. The adapter doesn’t include any settings and works right out of the box. Unbox it, plug it in, and pair the adapter to the car’s Bluetooth. It hardly takes 5 mins to get started. Wired Android Auto is always the best option for long drives as the WiFi affects the phone’s battery life, but for short trips, this adapter will make your job a lot easier. Overall, the Ottocast A2Air is a very useful and handy accessory to have in your car.
What I like
- Excellent build quality
- Plug & play operation
- Compact design
- No latency issues
- Regular OTA updates
- USB-C port
- Bundled high-quality USB cables
What I didn’t like
- Prono to scratches
- No companion app
- No OTA update alerts
- Doesn’t support quick switch
