Hi, I am having a difficult time in finding a good car mount which meets the following requirements: 1. Works with a case (Incipio NGP) 2. Can be rotated in landscape mode for GPS 3. Strong window sucker or good quality vent mount 4. Legs /feet /clamps must not block the power connector, speaker, mic, headphone, volume and sleep button. 5. Simple, secure and quick clamping method Thanks in advance.
