A:AnswerIt should show you when you put in your model of car as to whether you need one or not. I have a 2002 honda Crv that it was just put in. I did need an adapter and an additional wire. They installed it for free but the extras cost another $60 I believe. Maybe less.
A:AnswerYes this mounts in the dash. It is not one that folds or anything. It is a double din unit. My son has it and he loves it. Has good sound and call quality.
