How the Holder Works
Another issue with window mounts is the glare of the sun on the object which is particularly a problem when the object to be mounted is a portable satellite navigation unit or a mobile phone with satellite navigation capabilities.
Such objects need their screens to be clearly visible during use in the vehicle so that the directions they are providing are clearly visible by the driver, which is not the case when the screens are being obscured by the glare of the sun.
There is also an unresolved final issue with window suction mounts that police forces are endeavouring to combat. The window suction mount often leaves visible rings on the windscreen advertising to potential criminals that a portable satellite navigation unit may be present in the vehicle.
