The Effect of Window Tint on GPS Navigation

Window tint can interfere with GPS navigation.

Global positioning systems (GPS) use radio signals to communicate with satellites, so they are prone to interference. Some types of window tint can degrade your GPS signal, but probably not by much.

Identification

Some window tints contain metal, such as iron, which is very dense and makes it difficult for radio signals to pass through, according to BestRecovery.com.

Effect

How much window tint degrades the signal going to your GPS unit depends on the car and the type of tint, according to Tint Zone. Overall, even metallic window tint has little effect on your GPS unit.

Tip

If you want the best possible signal for your GPS unit, consider a non-metallic window tint, suggests BestRecovery. Dyed and ceramic tints are available and offer the same benefits as metallic window tint.
