To display GUI Texture only on main camera

Hi all, I am working on a game for android. I have 2 cameras in my scene. maincamera is following my car and another camera is showing me a top view of a car with Normalized view port rect in a small rectangle. When I am pausing my game a popup comes on the screen made up of GUITexture. It looks fine on main camera but it is also visible in 2nd camera which should not be like that.

Can any one help?

Yep. Put the texture object on it’s own layer - make the second camera not see that layer by changing its Culling Mask.
