Replacement GPS antenna for your Ford or Lincoln vehicle, new in packaging. This is not an authentic Ford part but we've been using these for years and they've worked great and are incredibly reliable. Please note, not all GPS antennas on eBay or Amazon that look like these will be compatible with Sync 3. It may look exactly the same but if the antenna itself has a wrong voltage, resistance, or bad grounding the antenna will throw a navigation fault error message on your Sync 3 display. This antenna is guaranteed to work with Sync 3.
