OK...mine will sit in the spring mount, but the pressure from the Ram case pushes on the gumdrop case & pushes on the ON-OFF switch, which shuts the ipad off. I assume you didn't have that trouble? I didn't see any way around that problem except to remove the gumdrop.

Then, there is no provision that I see to hook the power cable thru the gumdrop to power the ipad via vehicle battery. Does yours have something different? Maybe we have different Ram mounts. This is the one I have, called the "tab-tite". It's spring loaded.

Here's a Youtube of it's assembly:

Perhaps I'm missing something though.
