A GSM antenna is a cellular antenna that attaches to your car as well as your car's GPS unit. This enables the GPS unit to retrieve the appropriate guidance information. The antenna attaches to the roof of your car. You can attach it yourself even if you don't know much about electronics or automobiles.
Instructions
1. Locate a space on the interior of your windshield in which to place the rectangular GSM antenna. Make sure it won't be obstructed by metal objects and that it won't be in your way.
2. Clean and dry the area thoroughly with a cloth and water. Make sure the area is completely dry.
3. Peel off the adhesive cover from the back of the antenna and place the antenna vertically over the spot. Press down firmly to ensure that it sticks in place.
4. Plug one end of the included cable into the port on the antenna and run the other end to the exterior input port on the front of the GPS. You can unplug this cable when the GPS isn't in use.
