buildings, tunnels, underpasses, and forests. Bad weather may also effect the
signal reception. If your car window heat shield contains metal, the receiver will
not be able to pick up GPS signals.
3. All wireless communication products, such as mobile phones and speed limit warning
systems will interfere with the communication satellite and will affect signal reception.
