To connect a phone using the Bluetooth protocol to the Kia Sorento 2 with navigation, you need to do the following:
On the head device, you must select "Set Coupling through Phone" mode. On the phone, it should be included in the "Bluetooth" mode in the search mode of new devices.
After a while, the device will appear in the list with the name recorded in the audio system's head device. A password prompt is displayed on the phone. The default value for the head device is 1234. After you enter the code on the phone, the interface will be installed.
