Just a quick reply here. Received this mirror for my 04 yesterday and slapped it on. As has been previously said, it does widen the field of view; I sit pretty forward, so I can unfortunately see my face and not the driver's side window, but on the passenger's side, I can see through the whole rear side window, which helps with driving in Jersey (also helps to have the rear headrests removed too). The part# in total is 76400-BRM-000. One thing is that the blue tinting does darking the view a good amount, so today on a cloudy day when I was wearing sunglasses and looking through a tinted rear hatch, the view is quite dark. Just something to think about if you're looking to buy one. I still think it's a worthy thing to get.
