Hi I bought my Cx7 last year I'm the third owner.
I have found a concealed towbar behind a pop-off cover however I do not have the tow bar attachment I have asked the previous owner and didn't even know it existed.
My question is this a factory fitted item.
I have looked can not find a label to identify manufacture.

 

Photo?

Every genuine Mazda tow bar I've fitted since 2009 has a detachable tongue. Does the tongue mount vertically or horizontally?

Maybe pop into your local Mazda dealer and ask them to have a quick look at it.
