Double Din Radio Dash kit, wire harness and antenna adapter for installing an aftermarket radio.Very Important: Wire harness only works with standard non-premium amp factory systems- Not compatible with amp systems like Bose, Infinity, etc.- Red ignition wire of the new radio has to be run separately from the vehicle radio harness (factory radio plug has no ignition power wire). Will not retain some features like steering audio controls, rear DVD audio, etc- extra adapters required. Some off-brand radios might not be true Double Din Spec (slightly oversized/undersized) which means this kit will need to be modified or sanded down.
