Head-unit Account login screen with a red warning line about Wi-Fi or cellular data being subject to fees, a large QR code, and the instruction to open the BYD App and scan the code to log in. — The head unit shows a QR code that the BYD App scans to log the account in.

Head-unit account screen with a Log Out confirmation dialog asking Log out the current account? with a red Log Out button and a Cancel button. — Logging the vehicle account out from the head unit.

Cloud data management added#

Switched on by default.

BYD states that it takes the protection of your privacy and your data very seriously. As soon as the vehicle is connected to the internet (WLAN or mobile data), the system automatically uploads only the necessary, securely processed data to the cloud in order to ensure service quality and security.

The following three options can be viewed at any time and switched on or off individually under Settings > System settings > General > Cloud data management: Cloud service app, Analysis and Service Improvement, and Network security.

Head-unit System settings, General tab, with the Cloud-based Data Processing panel open and three toggles all switched on: Cloud service app, Analysis and Service Improvement and Network security, each with a short description. — The three cloud data options, all on by default, in Settings > System > General > Cloud-based Data Processing.

Head-unit Cloud-based Data Processing dialog explaining that cloud-based data processing is required for basic Vehicle System services, that the ON/OFF options can be set by the user, that details are in the BYD Vehicle System Privacy Statement, and that Vehicle System Cellular Data must be ON or WLAN connected, with an OK button. — The explanatory dialog: without cellular data or WLAN the basic Vehicle System services cannot be provided.

Android Auto and Apple CarPlay support added for selected countries#

Support is added for Croatia, Romania, the Czech Republic, Cyprus, Bulgaria, Slovakia and Serbia.

Optimisations#

Optimisation of the radio signal switching logic to improve the user experience#

New radio functions: the system supports automatic switching between FM and DAB and searches on its own for alternative stations with identical content, in order to improve the switching speed and the stability when changing station.

When the classic broadcast signal is weak, it switches automatically to streaming radio with identical content to keep playback uninterrupted.

Optimisation of the system UI display and the text messages#

A reset function has been added to the customisation screen of the navigation bar.

After “Restore settings”, Bluetooth is enabled by default.

Icons and themes: the map icon in the App Center does not adapt to the theme skins. It keeps only the uniformly rounded corners.

Navigation bar: with reverse gear engaged and the reversing camera active, the status bar can neither be pulled down nor tapped. A mask is also added to the dock, so that it cannot be clicked.

Head-unit System settings, Version tab, listing Version update – Upgrade, Version Details – View, Restore settings – Reset and Factory Reset – Reset, with the build number 13.1.33.2510254.1 shown next to a rocket illustration. — Restore settings on the Version tab is the reset that now leaves Bluetooth enabled.

Head-unit navigation bar customisation screen, Control tab, with a Done button on the left and a new Reset button on the right, above tiles such as Recent Tasks, Screen Rotation, Ventilate and Screen OFF and the hint Drag or tap the icon to add/delete. — The new Reset button in the navigation bar customisation screen.

Optimisation of the deactivation conditions for ICC, so that it can also be switched off when ICC is not activated#

ICC switch rules: in the inactive state the switch can be turned off. If the operation is not permitted, tapping it triggers the message “Please exit the ADAS first.”

Ending the driving assistance: with ICC active, pressing the brake in any gear.

Head-unit ADAS settings, Driving Assist tab, with Intelligent Cruise Control switched on, Inside Overtaking Prevention and Adjust Cruise Speed by Accelerator switched off, and a toast message Please exit ADAS first at the bottom. — The toast the head unit shows when the ICC switch may not be operated.

What we have not verified#

This is a translation of BYD Austria’s bulletin, not a test: we have not installed V2.0.0 on a Dolphin Surf.
The bulletin was published by BYD’s Austrian importer. The release itself is the European one, but roll-out dates are given for Austria, and a few items are country-specific (radio services, interface languages, legal notes).
Availability of individual features can depend on trim, model year and the head-unit hardware.
