Updated guide (2025) based on reports from partner workshops, spare parts dealers and motorists: symptoms, probable causes, solutions and prevention for infotainment, apps and OTA updates of BYD models.
✅ BYD Software & OTA Overview (2025): Strengths/Weaknesses
BYD models sold in Italy (e.g., the BYD Dolphin and BYD Seal ) offer a modern infotainment system with a large central display, Apple CarPlay/Android Auto integration, remote service apps, and OTA (Over-The-Air) updates to improve functionality, stability, and fuel economy. Strengths: generally fast boot times, connected ecosystem, and OTAs that introduce fixes and new features. Typical weaknesses: occasional interface freezes , Bluetooth/CarPlay instability, and OTA updates that sometimes interrupt or arrive in spurts.
- DiLink/infotainment : rich interface, user profiles, integrated navigation, smartphone connectivity.
- Modular OTAs : Update infotainment, T-Box (telematics), navigation/maps; in some cases also non-traction ADAS/ECUs.
- BYD App : Remote services (opening/closing, climate control, charging), notifications and scheduling.
🔧 BYD Software & OTA Main Issues (updated 2025)
Below are the most reported critical issues by the workshop/user network in 2024-2025 on BYD, with a focus on infotainment , CarPlay/Android Auto , apps/telematics , OTA and ADAS calibrations .
- Infotainment (freezes, reboots, slow UI)
- CarPlay/Android Auto (disconnections, audio, lag)
- BYD App & Telematics (Remote Controls, Notifications)
- OTA updates (interrupted download, installation errors)
- ADAS & cameras (warning, post-update calibrations)
- Digital dashboard/instrumentation (data synchronization)
- Time/cost table (workshop range)
1) Infotainment: freezing, rebooting and slow interface
- Typical symptoms: screen freezing during browsing/multimedia, random reboots, unresponsive touch, lag when switching apps.
- Common causes: Full cache, background apps, bugs after an incomplete update, USB cable/port with out-of-spec tolerances (if mirrored), corrupted profiles.
- Quick fixes: “soft” reboot the unit (= long press power button), clear cache and temporary data, check for available updates, restore settings (backup preferences), use certified “data” USB cables.
2) Apple CarPlay / Android Auto: disconnections, audio and lag
- Typical symptoms: CarPlay/AA won't launch first time, random disconnects, voice command latency, compressed or crackling audio.
- Common causes: non-MFi/USB-IF cables, dirty/oxidized ports, dual-Bluetooth conflict (phone + smartwatch), misaligned OS versions, power saving settings on the smartphone.
- Quick fixes: Try short MFi/USB-IF cable (0.5–1m), clean port and check clip, unpair/repair phone, update OS and apps, disable power saving while mirroring.

- Symptoms: App opening/climate not working immediately, SoC state of charge update delays, duplicate notifications.
- Causes: Low data coverage, GPS or T‑Box in sleep mode, limited app permissions, aggressive battery optimization on the smartphone.
- Solutions: Check location/notification permissions, disable battery optimization for the BYD app, perform a wake-up (open door/start ignition), check for telematics app/firmware updates.
4) OTA updates: download interrupted or installation failed
- Symptoms: Downloads stall, error messages during installation, updates not appearing for weeks.
- Causes: wave rollout (staggered release), low SoC battery, car not in stable park , weak network, insufficient memory space.
- Solutions: Run OTA with SoC > 40% , car parked and stable network (strong Wi-Fi or LTE), free up cache space, try again after rebooting the unit; if it persists, check in the workshop for an update via diagnostics/cable.
5) ADAS & cameras: warnings and calibrations after the update
- Symptoms: ADAS lights/warnings, 360° camera lagging or not starting, abnormal parking warnings.
- Causes: parameters not realigned after update, slight sensor misalignment, wiring/oxides on camera connectors.
- Solutions: realign parameters via diagnosis, check connectors/ground, possibly calibrate ADAS in the workshop.
6) Digital dashboard/instrumentation: synchronization and charging data
- Symptoms: Residual battery life not aligned with SoC, delay in consumption update, charging indicator “frozen”.
- Causes: Out of sync data layer, temporary post-OTA bugs, outdated energy parameters.
- Solutions: soft reboot, check available OTAs, update navigation/energy, possibly reset user profile (with backup).
💶 Approximate times and costs (from partner workshop network)
| Intervention | Cause/Symptom | Time / Range €* |
|---|---|---|
| Infotainment diagnosis + reset/clean cache | UI lag, sporadic crashes | 0.5–1 h €40–90 |
| Firmware update in the workshop (via cable) | OTA failed / unavailable | 1–2 h · €80 – €180 |
| Replacing the infotainment unit (head unit) | Persistent freezes/reboots | 2–3 h €420 – €950 |
| T-Box/antenna check + telematics realignment | Remote app slow or ineffective | 1–2 h · €70 – €150 |
| Cleaning/replacing USB connectors + testing MFi/USB-IF cable | CarPlay/AA unstable | 0.5–1 h €30–70 (+ cable €10–25) |
| ADAS calibration (post-update or warning) | Camera/Sensor Alerts | 1.5–3 h €120–260 |
*Ranges are indicative and vary by model, year, software level, part quality (OEM/Aftermarket) and local labor.
🧭 Quick Checklist for Smooth OTA Updates
- SoC battery > 40% and car parked in an area with stable signal (Wi-Fi is better).
- Clear infotainment cache and close background apps before updating.
- Do not interrupt power or network during installation.
- If the update fails 2–3 times, proceed to a workshop update (via cable/diagnostics).
- After OTA, check ADAS/cameras and schedule calibration if necessary.

❓ Frequently Asked Questions
How do I check if there is an OTA update available on my BYD?
Open the Settings > Updates menu and check for new versions. Alternatively, check the BYD app or the release notes on the display. Releases are often staggered , so it may take a few days for them to appear.
What do I do if the update gets stuck halfway?
Make sure your SoC is > 40%, network is stable, reboot the unit, and try again. If the error persists, take it to the shop for a cable update/diagnostics and memory/cache check.
Why does CarPlay/Android Auto disconnect?
In most cases, it's the cable: use a certified data cable (MFi/USB-IF), short and in good condition. Avoid low-quality hubs/surge adapters and disable battery saving on your smartphone.
Do BYD OTAs also improve range?
Sometimes updates include energy/climate optimizations and bug fixes that may impact battery life. After the OTA, monitor for 1-2 charging cycles.
🏁 Conclusions
Software is a key asset of the BYD 2025. Knowing the typical bugs , preparing the car for OTAs , and following the checklist avoids much of the inconvenience. In the event of persistent anomalies, the workshop network can perform wired updates, realignments, and calibrations.
