wherein the driving lever prevents the safety circuit unit from moving in a connecting direction at a provisional connector-engaging position, and wherein the driving lever permits the safety circuit unit to move in the connecting direction and is prevented from rotating by a flange of the safety circuit unit at a connector-engaging position.
7. The low-insertion-force connector assembly as claimed in claim 2, wherein the one connector is provided with the safety circuit unit slidable in a direction axially perpendicular to the driving lever, wherein the other connector is provided with a small connector for connecting with the safety circuit unit, and wherein the driving lever includes a groove engaged with a boss of the safety circuit unit,
wherein the boss is approached to engage with the groove by rotation of the driving lever in a state of disconnection between the safety circuit unit and the small connector, and wherein the groove corresponds to a sliding direction thereof so that the safety circuit unit operatively connects with the small connector in a state of connection between both the connectors while both the connectors are engaged with each other.
8. The low-insertion-force connector assembly as claimed in claim 7, wherein the boss of the safety circuit unit disengaged with the small connector abuts a side where the groove of the driving lever is formed such that the driving lever is prohibited to rotate in an engaging direction of both the connectors.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method comprising:
registering an identifier for a navigation application at a map management server;
accessing an installed version, at the map management server, of a geographic database according to the identifier;
accessing a later version, at the map management server, of the geographic database, wherein the later version of the geographic database is different than the installed version of the geographic database;
receiving, at the map management server, a destination location;
querying the installed version of the geographic database for the destination location for a first map result;
querying the later version of the geographic database for the destination location for a second map result; and
performing a comparison of the first map result and the second map result.
2. The method of claim 1, further comprising:
displaying a result of the comparison of the first map result and the second map result.
3. The method of claim 1, wherein the comparison indicates that the destination location is included in the later version of the geographic database and omitted from the installed version of the geographic database.
4. The method of claim 1, further comprising:
counting a number of times destination locations are omitted from the installed version of the geographic database; and
displaying the number in a message to a user.
5. The method of claim 4, wherein the message includes an offer to purchase the later version of the geographic database.
6. The method of claim 1, further comprising:
determining a location included in the installed version of the geographic database and nearby to the second map result from the later version of the geographic database.
7. The method of claim 1, further comprising:
providing a plurality of navigation options when the comparison of the first map result and the second map result indicates that the destination location is omitted from the installed version of the navigation database.
8. The method of claim 7, wherein the plurality of options includes at least two of a printout of full directions to the destination location, a printout of partial directions to the destination location based on the installed version of the geographic database, a transmission of directions to a mobile device, and a display of longitude and latitude coordinates.
9. The method of claim 1, further comprising:
transmitting the navigation location to a navigation system including the navigation application when the first map result is substantially equivalent to the second map result.
10. An map management server comprising:
a processor configured to register a navigation application of a user at the map management server and receive a destination location entered from a website;
a first database including an installed version of a geographic database, wherein the installed version of the geographic database is installed with the navigation application of the user;
a second database including a later version of the geographic database, wherein the later version of the geographic database is newer than the installed version of the geographic database,
wherein the processor is configured to query the installed version of the geographic database for the destination location for a first map result, query the later version of the geographic database for the destination location for a second map result, and perform a comparison of the first map result and the second map result.
11. The apparatus of claim 10, further comprising:
generating a display message based on the comparison of the first map result and the second map result, wherein the display message indicates that the destination location is included in the later version of the geographic database and omitted from the installed version of the geographic database.
12. The apparatus of claim 10, wherein the processor is further configured to count a number of times that destination locations are omitted from the installed version of the geographic database and generate an offer message when the number exceeds a threshold.
13. The apparatus of claim 10, wherein the processor is configured to generate a navigation message when the comparison of the first map result and the second map result indicates that the destination location is omitted form the installed version of the navigation database.
14. The apparatus of claim 13, wherein the navigation message includes options for a printout of full directions to the destination location, a printout of partial directions to the destination location based on the installed version of the geographic database, a transmission of directions to a mobile device, or a display of longitude and latitude coordinates.
15. The apparatus of claim 13, further comprising:

16. A non-transitory computer readable medium including instructions that when executed by a processor, instruct the processor to:
select an installed version of a geographic database installed with a navigation application from a list of compiled databases indexed by user;
select a later version of the geographic database from a map service;
receiving, at a map management server, a destination location;
compare, with respect to the destination location, the installed version of the geographic database to the later version of the geographic database; and
