SOFTWARE UPDATE
Why does my BYD SEAL show software version 1.0?
A SEAL showing 1.0 and “up to date” is saying that no update is currently offered to that car. Open the full system-version information and compare the complete package for your SEAL edition, rather than ranking the short number against another owner’s car.

Why the numbers can differ
Vehicle configuration, software branch, dealer-installed software and staged VIN rollout can affect the number and offer shown. Matching released EU and UK packages are owner-confirmed equivalent; the date each car receives an offer can still differ.
Check the installed release
Use these details to match the car to its release notice.
- Open the full system-version information while parked.
- Identify the vehicle edition and trim from its vehicle details.
- Compare the complete multimedia/system string with the notice for that car.
If the version still does not make sense
If expected functions are missing, ask a BYD dealer or BYD Customer Service to identify the installed full package and the update assigned to your car. Send the complete version-screen image, exact message, model edition and trim, last successful check and any dealer-installed update. A lack of an offer alone can simply mean your VIN is waiting its turn.
Safety note: unofficial firmware or resets used to force an offer can disrupt the car’s software; use the vehicle’s update process or BYD’s repair route.
