installing GPS antenna
- GPS antenna can be installed inside the car such as on top of the dash, or outside the car such as the roof
- GPS antenna must have a clear and unobstructed view to the sky. if the car window has some sort of film or tint on it, it may greatly reduce the strength of the GPS signal. in this case you should put the antenna outside the car instead
- caution: do not change the length of the GPS antenna, adjusting the length may short-circuit or malfunction
- caution: GPS antenna should be placed on a flat even surface if possible, for maximum accuracy
- caution: never place the GPS antenna in such a way that will interfere with the steering wheel or shift knob, for safety reasons
