GPS Signal Reception
WARNING: This page is about a different car, the 2011 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
The GPS signals obtained by the GPS antenna are provided by up to 24 different satellites. The audio-navigation unit supplies the GPS antenna with 5V through a coaxial cable to power the antenna's amplifier. The GPS receiver in the audio-navigation unit receives the amplified GPS signals back through the same coaxial cable. The GPS receiver identifies the satellites and processes the different GPS signals. These signals are then converted to actual locations by the audio-navigation unit in order to determine the position of the vehicle.
