I think you are looking at the air conditioning vet which is the grey part above the horn. That picture is taken at a very extreme position, in a normal seated position you cannot even see the horn.
The horn is actually the mini ID horn and disapears under the dash of the focus. In fact even people who know what they look like do not know that they are there, heck I got the car back from Matt and asked him when he was going to install the horns! (It was a long week)
