i decided to pay a bit more, and get a unit sold by usa companies. they are probably all made in china, but i wanted one with support. also, i made sure someplace like crutchfield had the harness and faceplate. a couple hundred bucks savings aint worth the hassle. crutchfield was a great help with the install. they had all the answers. even tho the instructions were good, little things came up, and it sure was nice to call and ask, and get the answer right away.
Be careful about cheap Chinese made car stereo or any worldwide sellers, their double DIN is international standard size, like 180 x 100mm, different from American size, so they won't fit for American installation kit.
