Calibration failures may be out of the following reasons: 1. The dash cam’s camera is too far from the car front, i.e. too close to the left and right sides or the upper and lower sides. 2. The car speed during most of the calibration process is less than 40 km/h. 3. The nighttime light is too dim to accurately identify the lane line. 4. The lane line is blurred and unidentifiable.

1.Please check the connection between the dash cam, power cable and car charger.
2.This situation might caused by unmatched voltage between the cigarette lighter socket and the dash cam. Make sure you use the standard power cable and car charger within the package in case of incompatibility issues.

If you cannot see the dash cam’s Wi-Fi hotspot name in your phone’s Wi-Fi hotspot list, please refer to the followings: 1. Make sure the dash cam’s Wi-Fi hotspot is on. If it is not, press the power button to turn it on. 2. Turn off the wireless LAN (or WLAN) and then on again on your phone’s system settings. After doing all above, if you still cannot find the dash cam’s Wi-Fi hotspot, please contact customer service onlinehelp@70mai.com

If you enter the wrong password when connecting the hotspot and try to input the password again in a short time, iPhone may recognize your operation as illegal. So that a pop-up dialog box “Cannot join the network xxxx (xxxx is Wi-Fi hot spot name) ” displays on the screen. In this case, please exit the password input interface, back to the Wi-Fi hotspot list, select the dash cam’s hotspot and then re-connect. If the above operation still cannot make a successful connection, please forget the dash cam’s Wi-Fi hotspot in your phone’s WLAN list then re-connect.

Any operation on the album when connected to the 70mai app 5. Detecting abnormity in the internal memory card, for instance, non-dash cam related files are detected. In this case, please format the internal memory card according to the voice prompts. The dash cam will automatically start recording when exiting the above operations.

Possible Reason 1: The dash cam’s positioning system fails to obtain positioning information and cannot generate driving record data. Solution: Check the status on the dash cam’s home screen. If the positioning icon is not shown, this is the reason. Bring the dash cam to an open space and wait for around 3 minutes before trying again. Possible Reason 2: The car did not move, so no driving record data is generated. Solution: Ensure that the dash cam is correctly installed in the car and working normally. Drive the car over a certain distance to generate driving record data. Possible Reason 3: Driving record data was not synchronized to the 70mai app. Solution: See the answer to “How can I synchronize the driving record data saved in the dash cam to the 70mai app?” Possible Reason 4: The phone has no network connection. When viewing driving records, the phone requires a network connection to load the map. Solution: Disconnect the phone from the dash cam’s Wi-Fi hotspot and connect it to a network (WLAN or mobile data network). Tap My > Driving route to enter the “Driving route” page to view the records.
