Firmware is the internal software that controls how a 70Mai Dash Cam operates. Depending on the model and release, an update may improve stability, compatibility, recording behavior, app integration, or supported features.
[note] Available update methods, menus, features, and release timing can vary by dash cam model, region, firmware branch, and 70mai app version. [/note] [reference] Title: Firmware Text: Internal software that controls the dash cam's operation and supported functions. Title: Firmware Version Text: The installed software version. Note it before updating so you can confirm the result afterward. Title: 70mai App Text: Used by supported models for Wi-Fi connection, device settings, footage access, and update-related functions. Title: Feature Changes Text: New firmware does not guarantee new features. Changes depend on the specific model and release. [/reference]What an Update May Change
Firmware releases can focus on different areas. A particular update may include only some of the following changes.
- Stability: adjustments related to startup, recording reliability, restarts, freezes, or general device behavior.
- Recording: improvements to loop recording, event handling, storage behavior, or file reliability.
- App connection: changes to Wi-Fi communication, device settings, or footage transfer.
- Compatibility: adjustments that help the dash cam work more smoothly with newer app or phone software.
- Features: model-dependent additions or refinements to supported camera, parking, GPS, voice, or connectivity functions.
- Software maintenance: bug fixes and other internal changes included with a particular release.
Check what is actually available on your model after an update rather than assuming every feature listed here will change.
Before You Update
Prepare the dash cam before starting. Stable power and a protected copy of important footage are the main priorities.
[checklist] * Dash cam has a stable power supply * Vehicle power will not be switched off during installation * Important accident, parking, or event clips are saved elsewhere * Memory card is operating normally if the model uses one * 70mai app is current before checking for an app-based update * Phone has internet access when the update needs to be downloaded * Current firmware version has been noted [/checklist]Keep Power Stable
Avoid starting an update when the vehicle is about to be switched off or when its power supply is unreliable. Keep the dash cam connected to its normal stable power source for the entire installation.
[warning] Do not unplug the dash cam, switch off its power, or remove its memory card while firmware is being transferred or installed. [/warning]Save Important Footage
A firmware update does not necessarily remove existing recordings, but important clips should be protected before any software or storage maintenance.
- Connect to the dash cam through the 70mai app if your model supports footage access.
- Save important driving, parking, accident, or event recordings to the phone.
- Keep an additional copy elsewhere when the footage is important evidence.
Check the Memory Card
For models that record to microSD storage, the card should be working normally before an update. A card that frequently reports storage problems is not a good starting point for maintenance.
- Back up important recordings before formatting a card.
- If formatting is needed, use the dash cam's available formatting function when appropriate for the model.
- If the model supports a manual memory-card firmware process, use a reliable compatible card and follow the exact file instructions for that model.
Check the Installed Firmware
Record the current version before updating. Menu names differ between models, and some dash cams do not have the same on-device interface.
From the Dash Cam
- Open the dash cam settings if your model provides an on-device settings screen.
- Look for an area such as About, Device Info, System, Version, or similar.
- Note the displayed firmware or software version.
From the 70mai App
- Power on the dash cam.
- Enable its Wi-Fi hotspot when required by the model.
- Connect the phone to the dash cam as prompted.
- Open the dash cam in the 70mai app.
- Check the device settings or available update area for version information.
Update with the 70mai App
On models that provide app-based firmware updating, the 70mai app guides the phone and dash cam through the download, transfer, and installation process.
[step] 1. Power the dash cam from a stable source 2. Enable the dash cam Wi-Fi hotspot when required 3. Connect the phone to the dash cam and open it in the 70mai app 4. Open the device settings or firmware update area 5. Check whether an update is offered for the connected model 6. Allow the firmware package to download when internet access is required 7. Follow the app instructions to transfer the package to the dash cam 8. Start or confirm installation when prompted 9. Keep power and the required wireless connection stable while the process is active 10. Allow the dash cam to restart and return to normal operation 11. Check the firmware version after startup [/step] [note] Normal recording or some controls may be temporarily unavailable while firmware is being updated. Wait until the dash cam returns to its normal operating state before checking recording again. [/note]If the App Shows the Current Version
If you expected another release but no update appears, use a few basic checks before trying again.
- Make sure the 70mai app itself is current.
- Confirm the phone has internet access when checking for a downloadable update.
- Reconnect the dash cam and reopen its device page.
- Check again after the connection is established normally.
Firmware availability can differ by model, region, or release schedule. A version discussed for one 70Mai Dash Cam should not be assumed to apply to another model.
Manual Memory Card Update
Some models may provide a manual firmware method using a memory card. Treat this as a model-specific method rather than a universal 70Mai procedure.
[warning] Use a manual firmware package only when the exact dash cam model supports that method. A package intended for another model or variant should not be installed. [/warning] [step] 1. Save important recordings before working with the memory card 2. Confirm that manual updating is supported for the exact dash cam model 3. Obtain the firmware package intended for that exact model and variant 4. Prepare the memory card according to the model-specific update instructions 5. Place the required firmware files in the specified location on the card 6. Insert the card into the dash cam while following the stated update sequence 7. Keep the dash cam on stable power while installation runs 8. Allow the dash cam to restart normally 9. Confirm the installed firmware version 10. Remove or clear the update files afterward only when the model-specific instructions call for it [/step]Feature Notes After an Update
Firmware can change how supported features behave. The areas below are useful to review after installation, especially when the release includes related changes.
Recording and Image Processing
Some releases may adjust recording or image-processing behavior, including:
- low-light or night recording behavior;
- noise handling in darker scenes;
- dynamic-range processing where supported;
- exposure or color processing;
- clarity of road details such as signs or license plates;
- general recording stability.
These changes are firmware- and model-dependent. They should not be expected from every update.
Parking and G-Sensor Behavior
For models with supported parking functions, an update may affect areas such as:
- shock or collision detection behavior;
- motion detection where available;
- available sensitivity settings;
- transitions between normal driving and parking operation.
Parking features and their required accessories vary between models, so recheck the options actually available on the connected dash cam.
GPS and Route Functions
On GPS-equipped models, firmware or app changes may affect:
- positioning behavior;
- route information shown in the app;
- speed or location information where supported;
- time synchronization associated with positioning features.
Voice Control and Languages
On models with voice control, a release may adjust:
- supported commands;
- recognition behavior;
- supported languages;
- availability of voice functions around other device operations.
Voice features differ significantly between 70Mai models and should be checked on the specific device after updating.
App and Interface Behavior
Firmware can also affect day-to-day interaction with the dash cam, including:
- Wi-Fi connection behavior;
- footage transfer and playback;
- device-setting availability;
- on-camera menus and prompts on models with a display;
- new or reorganized settings associated with supported features.
After the Update
Once the dash cam has restarted, check the settings and make a short recording before relying on it for normal driving.
[checklist] * Firmware version reflects the newly installed version * Date and time are correct * Recording resolution and quality settings are as expected * Frame-rate option is as expected where adjustable * G-sensor sensitivity is still set as intended * Parking settings are still set as intended where supported * GPS and speed-related options are as intended where supported * Voice control settings are as intended where supported * New video clips are being recorded normally * Playback opens normally * Audio is present when audio recording is enabled * GPS information appears normally on supported models [/checklist]Run a Short Recording Check
- Allow the dash cam to record normally for a short period.
- Open recent footage on the dash cam or through the 70mai app, depending on the model.
- Confirm that a new clip exists and plays normally.
- Check audio if recording audio is enabled.
- Check GPS-related information if the model supports it.
If an update introduced new settings, review them before assuming the previous configuration was retained. Some parameters can change or return to defaults after software maintenance.
Basic Update Checks
If an update does not complete as expected, start with simple power, storage, and connection checks rather than repeated forced attempts.
[troubleshoot] Problem: The update stops before completion Cause: Power may have been interrupted, the memory card may not be operating normally, available storage may be insufficient, or the wireless transfer may have been interrupted Fix: Restore stable power, protect important recordings, check the memory card if the model uses one, and retry the normal app update process. If card-related behavior continues, a different reliable compatible card can be considered. Problem: The dash cam repeatedly restarts after an update Cause: The installation may not have returned the device to normal operation or settings may need to be reinitialized Fix: Perform one normal power cycle. If normal settings remain accessible, a factory reset can be considered only as a later basic step when appropriate for the model. Avoid repeated forced restarts if the cycle continues. Problem: The firmware downloads to the phone but does not finish transferring to the dash cam Cause: The phone may have left the dash cam Wi-Fi connection, wireless strength may be weak, or network-switching behavior may have interrupted the local connection Fix: Keep the phone close to the dash cam, maintain the required dash cam Wi-Fi connection, prevent automatic network switching if it is breaking the transfer, keep the app open, and reduce other heavy phone activity before retrying. [/troubleshoot]If the dash cam remains in an abnormal restart cycle or cannot return to normal operation after basic checks, avoid repeated forced update attempts.
