* Please check compatible models on the Anshin Navi website.

*The "Family Safety Navigation App" may consume more battery power due to its location positioning specifications.

Please charge your smartphone and ensure sufficient battery power before use.

*Location accuracy may be reduced in areas with poor radio wave conditions, such as underground shopping malls, inside buildings, or in the shadow of buildings, as well as in GPS satellite environments.

The positioning information obtained through Safety Navigation depends on the accuracy of the device's measurement sensors and GPS; therefore, it cannot be used for purposes requiring high reliability.
