A:AnswerMost, if not, all cars will require an adapter. I own a 2003 VW jetta and I needed an adapter for the radio. You can find them online usually pretty cheap about $10 to $20
A:AnswerYes, you will probably need a different mounting bracket. I put it in a 2008 Toyota Yaris and used a different Mtg bracket. Fairly easy to install.
