Abstract: A method of operation of a navigation system includes: generating a potential route based on a navigation information, a status information, or a combination thereof; determining an update priority based on comparing a first map and the potential route on a second map with a control unit for identifying a discrepancy between the first map and the second map; and updating the first map based on the update priority for displaying on a device.

Abstract: An anti-dropping device and connection member, wherein the anti-dropping device comprises a connection member (40) and an anti-dropping boss (60); wherein the connection member (40) comprises: a first hole (42), which is adapted to a cross section of the anti-dropping boss (60) and configured to rotatably sheath the connection member (40) onto the anti-dropping boss (60); at least one second hole (44), which is configured to rotatably sheath a screw (10) into the connection member (40); and at least one connecting part (46), both ends of the connecting part (46) being respectively connected to the first hole (42) and the second hole (44); one end of the anti-dropping boss (60) is fixed on an apparatus (70) and is configured to fix the connection member (40) to the apparatus (70), thus facilitating operation and ensuring good safety during use of screws.
