There are a lot of wire connections in the back. This makes what should be a very easy install somewhat difficult. You have to bend the wires under the radio or it won't sit in the dash properly. After getting it into the dash I could see right away that the unit does not actually fill all the vertical space. There is space at the top and bottom. I decided I only wanted space at the top. I was able to realign it so the bottom was flush. The downside is that my unit does not snap into place. After driving with it for over a month it has not moved. I really would prefer to have it secured though.
