Cool - thanks, brothercannon!
Here's what the RAM-mount people said just now:
After a few emails with a colleague here that is most familiar with the operations of our mounts on motorcycles I have the following responses.
Below is his comment regarding the switching of the GPS from landscape to portrait mode.
The phone switches because an accelerometer senses movement in a certain direction and tells it to. I think if he tries to reposition the mount this might help solve the screen changing problem. I notice that when I hold my iPhone a certain way it tends to switch on me a lot.
And here is his reply regarding the vibration from the video.
I think it has a lot to do with the camera he is using. I do not believe that the iPhone 4 has and vibration dampening technology. The mount can only remove so much vibration. I have had this very same problem when using a point and shoot camera in video mode on a street bike. However, here is a video clip of me riding on some seriously rough terrain using a ram mount and camera that was made for extreme video. You tell me if you see a difference….
This video is shot at 720p or lower I think. But despite the lower resolution there is still less vibration.
Have you tried a different location on your handlebar to mount the phone? You may receive less vibration the further you are away from the forks."
