One of the latest is a brand called Herilary. Its newest product, launched as Herilary C2, is a wireless Android Auto adapter whose purpose is to transform the wired version into a cordless experience. It does the same things as all the other adapters currently on the market, though the parent company claims CarPlay is also supported (it's still unclear if this claim is also accurate, as I haven't tested it, but adapters to convert wired CarPlay to wireless are nothing new).
This new adapter works exactly like you'd expect it to work. First of all, you must plug it into the USB port of your car (it supports USB Type-A and USB-C, thanks to an included adapter). It powers on when you start the engine.
Next, you must connect your smartphone to the adapter using Bluetooth (Wi-Fi also needs to be one, as it’s an Android Auto wireless requirement). When the pairing is complete, Android Auto should start working wirelessly, with the interface to appear on the dashboard screen without you plugging in the smartphone.
The number one benefit is the permanent connection, as you can leave the adapter connected and have Android Auto launch wireless whenever you turn on the engine.
AAWireless pioneered this product category not a long time, and the arrival of Motorola's MA1 provided customers with one extra choice. Since then, several other companies have joined the battle, including more generic names from China, but all adapters work similarly and come with the same purpose. At the end of the day, converting Android Auto wired to wireless helps get rid of the cable, but at the same time, also avoids all the problems that are typically produced by a wired experience.
Android Auto cables could often cause problems for users, as they lead to connection problems, random disconnects, and crashes in the middle of the drive. It might seem easy to find a high-quality cable to run Android Auto, but the whole thing is much more complicated, especially because even the cords that ship with phones end up malfunctioning occasionally. Google has created a guide to help users choose the right cable, with the company even experimenting with a troubleshooting feature for Android Auto to determine if the cord isn't working correctly. This option is yet to launch in Android Auto, and it's currently unclear if Google is still working on it right now.
