b.Installation Instructions for Vehicles with Aerial Type Roof Mounted FM Antenna. For vehicles where the FM radio antenna is located on the front or rear of the roof of the vehicle, the FM Extender Cable should be mounted horizontally on the front or rear glass below the FM antenna, or installed into the headliner of the vehicle under the FM antenna.
•If you are installing the FM Extender Cable on the window glass, attach the suc- tion cups to the glass under the FM antenna in a horizontal orientation. The wire between the two suction cups should be pulled taut and as straight as possible, and should not obstruct the driver’s view. (Figure 20)
•If you are installing the FM Extender Cable into the headliner, remove the suction cups and tuck the wire into the headliner, stretched taut and straight, and cen- tered under the FM antenna.
