Car navigation factory settings do not have a fixed password. The initial navigation passwords produced by different brands may be different (for example, Gefei brand's password is 3368, and Castrol's password is 7253), and even different batches of passwords are a little different (Castrol's old password is 7253 and the new password is 8888). Therefore, if you want to know the navigation factory password of the car, you need to refer to the user manual.

Steps to restore the factory system through vehicle navigation:

1, most navigation has a reset button, which should be a small hole.

2, navigation has a rest hole, just insert something for a few seconds.

3. If not, it is in the function table, the lower right corner, or the system settings.

4, then plug in the power supply and wait for a few seconds, and finally loosen the toothpick to restore the factory settings.

5. However, all online settings must be reset, especially online accounts and passwords. After the factory settings are restored, the account and password entered into the router will also be restored to the factory settings.
