GREAT instructions! I just used them to install an XM radio on my Fit. The only difference was I routed the antenna through the grommet on the hatchback. Yay! Tunes!!

 

My antenna was mounted in the front just back of the windshield in the center. Ran the wires under the weatherstripping and under the dash. Not as good as a factory install, like my Camaro has, but still, better than nothing. Easy to change if you sell the car, which I do NOT intend to do.
