BYD previously announced that it would work with five apps to include Huawei HiCar on its in-car system DiLink.
Huawei HiCar enables Huawei phones to connect wirelessly to the car, allowing users to control their phones from the center console. The update also includes Remote Parking Assist and Music Ambient Light.
The features of this updated Huawei HiCar include maps, phone, music, news, and are adapted to the hardware in cars.
The Huawei HiCar service is parallel to BYD's DiLink, and users can choose whether to use HiCar or DiLink depending on their needs.
Earlier this month, a photo widely circulated on the Chinese Internet showed a Han EV that had received that OTA push, but the update was not officially pushed by BYD on a large scale.
BYD released its in-car system DiLink 3.0 in August last year, adding new features including NFC mobile keys and voice assistants.
Huawei HiCar is Huawei's phone and car interconnection feature, similar to Apple's Car Play.
