A:AnswerI believe it will fit any vehicle but will require a dash kit that is specifically made for your Hyundai Santa Fe. I installed this radio in my Toyota 4 Runner and it fits perfectly with the dash kit made for my SUV.
A:AnswerI installed the unit in my 2003 Nissan Truck. Does your vehicle radio space a 2 DIN or 1 DIN space? A 2 DIN is a wide opening for fitting. A one DIN is a single space opening. If your stock radio is small, you probably have a single DIN space. The unit you are interested in is a 2DIN and it will not fit.
A:AnswerI attempted to install system myself, and did a fairly good job. I didn't have have a special crimping pliers do I took it to local audio installation and they finished the job.
