When replacing the radio and display receiver assembly, always replace it with a new one. If a radio and display receiver assembly which was installed to another vehicle is used, the following may occur:
A communication malfunction DTC may be stored.
The radio and display receiver assembly may not operate normally.
Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Audio and Visual System.
Check that the following "Wi-Fi" connection setting conditions are met.
"Wi-Fi" connection setting is turned on
Communication setting is set to "Wi-Fi"

Check the conditions and procedure for establishing a "Wi-Fi" connection, and perform "Wi-Fi" connection again.
As there may be wave interference, disconnect other "Wi-Fi" compatible devices (Miracast compatible devices) or "Bluetooth" compatible devices before establishing a "Wi-Fi" connection.
A "Wi-Fi" connection can be established manually or automatically.
There are 3 ways to establish a manual connection: Connecting using simple setting, connecting by searching for a "Wi-Fi" access point and inputting a password, and connecting by inputting an SSID and password.
Even though an automatic connection is enabled, a connection can be established only when a "Wi-Fi" access point with the same SSID and password that were used for a previous connection exists.
It may not be possible to establish a "Wi-Fi" connection in a region other than the region where the vehicle was purchased.

Bring a portable device to be used to establish a "Wi-Fi" connection into the cabin and perform "Wi-Fi" connection again near the in-vehicle device.
Considering the radio wave environment around the vehicle, move the vehicle and establish a "Wi-Fi" connection.
Depending on the portable device, operation by the customer (Internet sharing, tethering settings, etc.) may be required each time a "Wi-Fi" connection is established.

Check the condition of portable device.
The head unit may not be able to connect to the access point due to the condition of the portable device (e.g., the power may not be turned on, tethering may be turned off, or the SSID (name of access point) may not be sent).
When the power of the portable device is turned off, tethering may be turned off.
