What are the dimensions of...

[Shehadehd]

Okay, this might be a long shot... But does anyone here own a BMW with an idrive navigation system? I need to know what the dimensions are for the idrive controller? The dimensions I would need are the length, width, and depth of the controllers shown below. I think there are other versions, and If anyone knows what those dimensions are I would really appreciate it.

Thank you in advance!
