I bust mine just 3 weeks after having the car. I caught it on the side of the garage reversing out, because I was concentrating more on the aerial hitting the roof. Although the whole unit fell to pieces on the floor, and scouring the glass, the only piece that needed replacing was the glass, and Ford dealer got the glass the following day and fitted. It cost around £33, remember it is a heated unit. Pop it into your dealer and let them ascertain whether the casing can be salvaged. Good luck.
