Reasons why dash cams do not display location and speed
GPS coordinates are recorded during camera operation but in some cases this signal cannot be "captured" when using the vehicle.
What is a dash cam?
Dash cam (also known as dash cam) is a device that records images and sounds while the vehicle is moving. Information will be transmitted directly to the driver while participating in traffic, broadcast remotely to those with access rights via wireless waves and stored in the device's memory.
Using metal insulation film, the car is in an area with blocked signal, bad weather are reasons why the dash cam does not show GPS coordinates.
Dash cams also have the function of observing traffic at night, giving directions via GPS system, reading traffic signs, warning and measuring the speed of road vehicles.

Reasons why dash cams do not display location and speed
Using metal insulation film, the car is in an area with blocked signal, bad weather are reasons why the dash cam does not show GPS coordinates.
First, the most common is some types of heat-insulating films coated with a layer of metal to block heat, because the sunlight is reflected back when shining on the film, preventing ultraviolet rays from entering the car. However, this type of film can cause interference with electronic and radio devices such as phones, devices with Bluetooth connection, radio, automatic toll card readers, GPS.
The signal interference can occur more or less depending on each device and different car models. If the dash cam does not display GPS coordinates, the car owner can try by lowering all the windows. If the coordinates appear again, it is likely that the cause comes from the heat-insulating film. The solution to solve the above problem is to change the heat-insulating film to a non-metallic type.
The second reason is bad weather. GPS signals are transmitted from satellites outside the atmosphere, so if the weather is bad, cloudy, the dash cam may not receive the GPS signal. In addition, there are other factors that hinder the signal such as the car moving between skyscrapers, tall trees in the forest, valleys, hills, tunnels, bridges. The GPS signal will be restored when the driver drives out of these areas.
Finally, other electronic devices inside the vehicle can also interfere with GPS signals, especially devices that are not manufactured to the correct electromagnetic standards. These devices can include cell phones, display screens, and radar detectors.
