Among GPS accessories, brackets are the most prone to problems, especially suction cups and back clips. Many car owners report that the quality of the bracket sucker is not good, and the adhesion is completely unstable, and it falls off after a slight bump. The back clip is also very easy to break, and it will break as soon as it is broken.

　　In fact, the loosening of the suction cup usually occurs after a period of use. When the air gas enters the circular gel part of the suction cup, the solid empty part will leave an empty gap. The larger the air gap, the lower the adhesion, and the easier it is to fall off. Frequent sticking and pulling can also reduce the attachment function of the suction cup. The owner can wipe the contact position of the front windshield and the suction cup of the navigation bracket to reduce the empty gap left by the real empty part. If the loose time is too frequent, the GPS bracket should be replaced to avoid potential safety hazards.

　　But posterior clip fractures are more caused by human factors. The owner's improper disassembly method makes the originally weak back clip more easily broken. When disassembling, pay more attention to the direction reminder on the rear clip. Too bad it's really broken. You can choose a universal bracket to replace it. 4.4: The GPS screen is slow to respond

　　Touch screen has become an indispensable part of our life, and GPS is one of the first electronic products to apply touch screen technology. The slow response of the screen will not only affect the query effect of handwritten input, but may also cause deviations when clicking on the query. There are generally two types of unresponsive GPS screens:

　　1. The screen is damaged by sharp objects.

　　2. The screen recognition is biased.

　　To determine why the screen is slow to respond, you can choose to manually enter a place name while searching for a destination. If the words in the handwriting box are always choppy, incoherent, or even divided into multiple parts. Then the touchscreen is likely to be damaged by sharp objects. Usually, this situation will only appear after using for more than half a year, and there is no solution. The key lies in the usual use and maintenance. When handwriting, choose to use the stylus that comes with the GPS, try not to tap the screen with your fingertips for a long time or use a pointed toothpick as a substitute.

　　However, the deviation of screen recognition is generally reflected in the inability to accurately identify the user's click range. For example, when the car owner selects a route, he clicks on the "optimal route", but the GPS recognizes it as the adjacent "high-speed priority". The screen can be readjusted at this point. General screen adjustment is under "Settings", GPS of different brands will be slightly different. Enter the calibration menu, after the "cross" calibration symbol appears on the screen, point the stylus to the middle of the cross, and click according to the prompts.
