GPS car navigation systems can either be factory-installed on brand new automobiles or bought as an add-on accessory. GPS car navigation systems operate by utilizing the signals from the satellites with interactive on-board map. There are some GPS car navigation systems which are interlinked with traffic information sources that facilitate them to automatically take into account certain vital factors such as construction and congestion when determining the best travel route. GPS car navigation systems can also provide voice or visual instructions that can help drivers while travelling.
