According to my understanding, the original 2016 K3 GLS AT car is equipped with Bluetooth function. Bluetooth technology has become one of the common features in modern cars, which allows drivers to play audio, make phone calls and other operations with the in-car entertainment system through a wireless connection. Therefore, your 2016 K3 GLS AT should be Bluetooth-enabled, making it easy to connect your phone or other Bluetooth devices.
The original car has Bluetooth function, the old one does not!!
