As Icedog_16 mentioned din is din and what you have in the picture is what is called single din. There are 1.5 din and double dins out there and they are all pretty common. If the HU you are talking about is what is in the picture than it is a single din. It needs 2 small pieces of bent wire to remove that should have come with the HU/car. Most after market HUs like Alpine for instance will come with a trim ring that snaps in place after you install it. That makes up for the difference in the face size between what you have in the picture.Could someone do me a big favour?
