My BYD Seal showing my software version is 1.0

Is version 1.0 the most up to date software for my Seal ? Car showing is up to date.

You will need to check the system version of your BYD Seal in settings, the latest version is commonly known as 2503 but if you bought the car recently then it could also have 2501.

Version 1.0 means that your vehicle has not been updated OTA (over the air), but your dealer might updated using USB instead.

Many people still awaiting updates, so might be good idea to contact your local BYD dealer.
