This one hooks up wirelessly through the little hershy bar shaped device. It must be at least six feet from the antenna in a straight line. I put it under the side of the Weathertech mat on the passenger side next to the trans tunnel. The antenna and the bar cannot have a line if sight through glass to one another. The antenna must be mounted on metal. I mount it on the roof on the drivers side out the rear hatch. I bought an external antenna mount...but there was a through-glass line of sight...nope. Some of these rules sound crazy, but when you follow them all the lights go green and you can surf the Internet, stream music, text, and (heaven forbid) make a phone call. Works with any cell service as far as I know. It works with my wife’s Verizon work phone and my AT&T.
