In fact, the loosening of the navigation cable plug usually occurs after a period of use. When the circular colloid part of the sucker enters by air, a gap is left in the empty part. The bigger the gap, the lower the adhesion and the easier it is to fall off.

Frequent sticking and pulling will also reduce the attachment of suction cups. The owner can wipe the contact position between the front windshield and the suction cup of the navigation bracket to reduce the gap left by the vacuum part. If the loose room is too frequent, the GPS bracket should be replaced to avoid potential safety hazards.
