The smartphone is instead of a radar detector!? Can the "Orvis & crackdown" app really be used?

　The current situation of speed crackdowns, such as the expansion of the installation of "Moving Orvis", has changed dramatically, but at the same time, the driver is taking measures such as installing a radar detector, including self -defense.For this reason, these products are not as good as Dora Reco.

　On the other hand, many users are stepping on the price of the radar detector.I would like to recommend using a smartphone for such users!Here are some of the more smartphone apps that have been increasing and can get crackdown information.Sentence / Masahiro Takayama, Photo / Masahiro Takayama, Best Car Editorial Department

■ It does not "detect" radar etc.

　First of all, I would like to first confirm that the apps introduced this time do not "detect" Orbis and other radars.

　The head family, the "radar detector", receives radio waves emitted from the crackdown aircraft and conveys its existence to the driver, but the idea of the app is "Using GPS, displays crackdown information from the recorded database, and warns."

　Naturally, regardless of the "reception sensitivity", etc., "Which timing (distance, etc.) to promote caution (caution)" set on the app side, "GPS reception accuracy (many parts depend on the smartphone side)" and above all."Database (information) accuracy" is also important.

　This time, "Yahoo! Car Navi", which is very popular as a free smartphone navigation app, has newly implemented a function called "Speed Caution Information Plus".This app is the first billing system (250 yen per month), but the accuracy and functions are high as long as it is charged.

■ It is also important to use alone or background

　The application introduced as described above is transmitted to the driver by placing customized crackdown information on the map screen (often on Google Maps) on the map screen.

　Some of these have a navigation function like Yahoo! Car navigation, but the car navigation function itself is usually very common, in other words, there is almost no congestion avoidance using VICS.

　The point is to use these apps in the "background" while displaying the car navigation app.

　The visible screen is the car navigation application, but when approaching the crackdown point, it will inform you by voice or pop -up display on the screen.

　I usually use the crackdown app in the background in addition to some car navigation apps.Even if the navigation application is also displayed, many are fixed -type, and the motion, rat catching and checking information are more reliable in the precision.

　However, since the two apps are moved at the same time, 1) the battery is consumed faster 2) the heat generated by the main unit is increased, and depending on the application, the guide is jumbled and it is difficult to understand.

　For these, it's best to have them actually experience the combination with the navigation apps that you mainly use.Of course, if it is to leave the car navigation to the car navigation system, there is no problem in using it alone.
