Here is a mobile phone holder which has not blush before other more expensive. I bought it because it has a "flexible tube" that allows him away a little of the windshield, which is useful on some minivans. It is strong enough, even if he is certain that he will not last the entire life of the vehicle (usually have suction cups which eventually turn yellow and lose their grip).
It fits in width to many smartphone, but probably not larger displays GPS. But for my use it is perfect.
