I installed DirecTV (KVH TracVision A7) with local channels in my Acadia about 3 weeks ago. I decided to wait and post after I had enough time to evaluate the product. It works as advertised. I do experience about a 1 second interruption when driving under and underpass or when there are tall trees close to the road that blocks the southern view of the sky. I haven't been near any tall buildings, but I would assume the reception would be spotty. I did the install myself, about 2 hours the first evening and 2 hours the second evening. Pictures are posted in the picture share area.
