If you're tired of plugging your phone into a cable every morning to use Android Auto, the solution is simple: you can make your car's system wireless Android Auto with a small palm-sized adapter.

How does the adapter work?

Requirements: Your car must already support Android Auto (wired version).

Installation: Plug the adapter into the car's USB port.

Setup: Configure the adapter with your phone only the first time, then it will work automatically on startup.

The adapter acts as a mediator between your phone and car:

When entering the car, the phone connects to the adapter via Bluetooth to identify the device and share connection data.

The adapter creates a local Wi-Fi Direct network (preferably 5GHz) to transfer heavy data such as maps, music, and the screen.

Automatic connection is established without the need to plug in a cable each time.

Advantages

Ease of use: No more searching for cables.

Fast automatic connection: When you start the car, the system automatically connects to your phone.

Flexibility: No need to modify the car's system or buy a new car.

Disadvantages or warnings

Battery drain: Wireless connection using Wi-Fi Direct consumes more battery compared to wired connection, especially when using maps or streaming music, so it is advisable to charge the phone during long trips.

Connection speed: Although wireless connection is effective, it may be slightly slower than wired connection, but it is suitable for the vast majority of daily uses.

Conversion is not possible if your car does not support Android Auto from the start.

How to choose the right adapter?

Choose an adapter that supports Wi-Fi 5GHz to reduce latency and ensure better transfer speed.

It is preferable that it has a detachable USB cable so as not to obstruct other ports or spoil the console's appearance.

Avoid adapters that only support Wi-Fi 2.4GHz as they are slower and more prone to interference.

Popular brands: Carlinkit, AA Wireless, Ottocast, Motorola… but focus on specifications rather than just the brand.
