Global Positioning System is short for GPS, which is a satellite-based system. GPS makes use of the radio signals in order to send and receive information. Since a GPS receiver receives information from satellites, it’s prone to interference. For instance, window tint may have a negative impact on the GPS signal; however, the difference won’t be significant.

Window Tints

Window tints aka window films are thin laminate films. They are designed to be installed on the glass interior or exterior in boats and automobiles. You can also find them on the glass used in homes, such as the glass of windows. Usually, Polyethylene Terephthalate (PET) is used to make window tints since this material is stable, strong, clear and is compatible with different types of surfaces.

Generally, window films are divided into different categories based on their parts of construction, application, substrate type and technical performance.


As said earlier, some window tints may contain metal like iron. Since iron is dense, radio signals find it hard to pass through this metal. Therefore, you may not get a stronger signal in your home, which may or may not be a problem for you.


According to a report from Tint Zone, if you want to find out how much your window tint will affect your GPS unit, know that it depends upon the GPS unit installed in your vehicle or home and the tint type. All in all, even if you have a metallic window tint, the effect won’t be very significant. However, it will make some difference.


So, what can you do to ensure you get the best signal possible? Well, here is a tip: you can get the strongest signal if you opt for a non-metallic window tint. For instance, you can consider ceramic or dyed tints as they have many features in common with metallic window tint.
