I went with the universal because of price and I wanted the dome lights. Added the marine shield . Had to add to the outside of the box a little to do it .
Added an external antenna , the one that came with it may have worked it was not all balled up on the inside of the box .
Taking the stereo out was a huge pain . Swamp Donkey told me it was just keyed into the frame . NOT, it was screwed and taped . Had to take out the speakers to figure that out .
Very happy with it . Loud enough for 55 mph driving . Sound quality is fine with me .
