Is there anything inside the front grill plastic Mazda Logo crest?

I had taped a Logo Emblem on the face of the Mazda Logo and was told that it would interfere with the radar control that is in effect when using the cruise control that automatically keeps a distance between my car and the one in front of me. I wanted to make sure that my placing that emblem there it would adversely affect that function. What say you. Don't place it there or it's OK to place it there? Thanks for any help.

I certainly would not place anything that does not belong there in that area. It's not worth the variable of affecting proper operation.
