How to fix a dash cam that keeps falling off your windscreen UK

To stop your dash cam falling off the windscreen, use 3M adhesive tape with a bonding promoter for maximum hold. Before installing, thoroughly clean the windscreen area with isopropyl alcohol and ensure it's completely dry. For suction cup models (like some Nextbase models), slightly moisten the cup before attaching. When positioning your dash cam (such as popular UK models like the Garmin Dash Cam Mini 2 or Nextbase 622GW), mount it centrally behind the rear-view mirror to maintain optimal field of view while complying with UK motoring laws. Avoid blocking the driver's view as this could result in an MOT failure. Replacement mirror-style dash cams (like the Halfords HDC400) can be fitted directly over your existing rear-view mirror.
