Notice: 1. It should be possible to see the wide sky without obstacle for GPS
satellite reception.
The obstacles same as high building area, cliff and leaves what can
cover the sky makes it need additional time to calculate exact location than
normal areas.
Locate the GPS Antenna always to the place good to see the sky.
2. Rainy day (especially, with thunder and lightening) cause delay time to
calculate location than normal weather.
3. Especially, in case of metal coating on the glass of car front, it is
impossible to show location due to the Satellite signal blocking by metal
coating. (Satellite signal can’t pass the metal)
