Best 3.0 universal connect wireless carplay screen adaptor

In recent years, wireless CarPlay has been used by more and more users, and more car makes and models are supported. Everyone has fully enjoyed the convenience that wireless CarPlay brings to us.

What is the connection order of wireless CarPlay?

The most intuitive difference between wired CarPlay and wireless CarPlay is the data cable, wireless CarPlay does not need data cable connection, it uses Bluetooth and Wi-Fi.

?The general process is below:

• iPhone and car Bluetooth connection (discovery, setup, pairing, etc. process)

• The car sends Wi-Fi credentials to the iPhone

• After the Wi-Fi connection between iPhone and car is complete, the CarPlay session is created

• Bluetooth disconnection

Above are a few steps outlined, but of course there are some detailed processes in each step.

After reading the above process, you should have a general understanding that wireless CarPlay relies on Bluetooth and Wi-Fi, and Bluetooth will be disconnected after the CarPlay session is created (CarPlay can be used normally now). Simply put, Bluetooth does the prep work, and when it's done, Bluetooth is no longer needed.

If you are using wireless CarPlay, you can observe if your Bluetooth and Wi-Fi are turned on by your iPhone when you get in the car, and your Bluetooth is disconnected when your car's center screen shows the CarPlay interface. Even if it's not disconnected, it won't affect your CarPlay usage if you turn it off manually.

So why disconnect? The reason: to avoid interference

With the wireless CarPlay we currently use, most Wi-Fi only supports the 2.4 GHz band, and Bluetooth uses the 2.4 GHz band, so if the two frequencies overlap, they will interfere with each other, including but not limited to slow connection, no connection, weak signal, Bluetooth audio skipping, etc.

Wireless CarPlay, on the other hand, relies on Wi-Fi, so if there is interference, it may lead to slow data transfer, resulting in lag. Or slow connection speed, not connecting, etc. So Apple will require CarPlay to disconnect from Bluetooth when the connection is complete, in order to avoid interference.

Except disconnecting Bluetooth, another solution is to use Wi-Fi that supports the 5GHz band

CarPlay with 5GHz band Wi-Fi support is still relatively rare in cars with original car units. The third-party CarPlay modules or adapter boxes (wired CarPlay to wireless CarPlay) that are available on the market already partially support it. It is recommended that you choose this kind of 5GHz CarPlay support when you purchase. The reason is:

• More channels for wireless use

• Less interference from other wireless systems

• No crowding

In the car, we also use some wireless devices ourselves, such as our Apple Watch, car recorder, car audio (DSP) devices and so on. These devices all require Bluetooth or Wi-Fi, so there is the potential for interference, slow speeds, poor connections, interruptions, and so on.

Pro Tips: If you are using wireless CarPlay and encounter a similar phenomenon, you can check if the interference is caused by other wireless devices.

Except wireless CarPlay, the following phenomena can exist when we use wireless devices on a daily basis

• Any of the following symptoms can be caused by interference from Wi-Fi or Bluetooth signals.

• The device does not connect or does not stay connected

• Slow connection speed and weak signal strength

• Bluetooth audio jumps forward, is intermittent, interrupted, or has static or buzzing noises

• Erratic or "jumpy" pointer movement

Common microwave ovens, fluorescent lights, wireless cameras are sources of interference, if you are using a wireless mouse, wireless touchpad, wireless keyboard, there may be lag, unstable mouse pointer, jumping, etc. Try to stay away from these sources of interference, or closer to your Wi-Fi router or Bluetooth devices. There is also the use of 5GHz band as much as possible.
