IMPORTANT: Some mapping software or GPS navigation software may not be compatible with
the device, please consult with the software provider/retailer before installing the software.
Receiving Better Satellite Signals
GPS positioning is limited by bad weather (e.g. rainy or cloudy days) and usage
location (e.g. tall buildings, tunnels, underpasses, trees, bridges...etc). Typically, GPS
does not work indoors, nor can GPS signals penetrate buildings, car sun shades and
heat reflective film with metallic content.
It can take several minutes the first time you establish a GPS connection. If you find
the device can not detect the satellite signal, try the following:
• Move the device to an open space without tall buildings or trees around it.
• Make sure there are no wireless communication products (e.g. radar-detecting
devices and mobile phones) nearby since these products may cause unstable signal
reception.
• Connect an external Bluetooth GPS receiver (not included in the package) to the
device in order to enhance the reception.
Important Notice about Using GPS
• The GPS is built and operated by the US Defense Department. The accuracy of
location data may be affected by changes made by the Department.
• GPS should not be used for precise location measurement. It can only be used
as a navigation aid.
• Do not turn on the car engine when the device is connected to the car charger (not
included in the package) as this may damage the device.
• Make sure the DC voltage provided by your car and the electric current supplied
from your car charger are compatible with the device before using them.
• Using the GPS may drain the battery faster than usual.
