I installed a sportster on my gx and love it. The antenna is mounted on the roof, left rear at the base of the roof rack rail. Ran the line for the antennae through the headliner and to the center console. I put the base in the center console and rant the power supply to the fuse box so I didnt have to use the cig adapter. The results are awwsome. With the cover to the center console closed, you can't see it from the outside. Also, since the roof line is so high, you cannot even see the antenna. Be sure to leave about two feet of cord for the antenna and power supply to the base in the console so you can take the unit out and change channels, etc while you are in the car. Good luck.
