Matching the release number
BYD Norway lists V3.2.2, May 2026, short multimedia version 260413, as a revision of 3.2.0. Its separate 3.2.3 entry describes a weak-network stability improvement.
The retained BYD Denmark source labels full system version 51.1.4.2604130.1 as 3.2.3 and lists camping mode, third-generation microphone support, assistant languages, a maximum towing-speed setting, a trailer-light warning with connected wiring, plus interface, phone, radio, climate-fan and translation refinements. These sources use different release labels and descriptions; compare the full version and notice in your own car rather than assuming the short numbers are interchangeable.
Installing the offered package
Matching released EU updates apply to matching UK cars, as confirmed by UK owners. The offer can arrive at a different time for each VIN; use the package offered by your car.
- Park where the car can remain unused for the duration shown by its update prompt.
- Read the car’s notice and compare its complete system version with the matching release record.
- Meet the battery and connection requirements displayed by your car.
- Start or schedule the update through the vehicle’s screen. Safety note: leave installation running as instructed; interrupting it or using unofficial firmware can disrupt the car’s software.
- Wait for the completed-update message.
- Check the new scene modes and any supported trailer settings while parked; normal controls should be available again.
If the update fails
If installation reports a failure or a warning persists afterwards, follow the on-screen message and contact a BYD dealer or BYD Customer Service. Give them the full system version and exact error, and ask them to check the failed package and recovery required. If only the version label differs, ask them to identify the release for that full package.
