Do you need an external GPS antenna or GPS sensor?
Usually you don't need an external GPS if your multifunction display has an integrated GPS receiver. However, there are certain circumstances when you may need an external GPS antenna or sensor - for example, in spaces where the multifunction display does not receive or has limited reception of GPS signals.
