For those dashcams that are "GPS-Ready" but do not include their own built-in GPS antennas, please see the following listing of GPS antennas for GPS-ready dashcams.

These external dashcam GPS antennas plug directly into the compatible dashcams (please see the specific product details for compatibility listings) and these external antennas provide GPS satellite signal to the dashcam so that the vehicle's speed and position will be logged automatically to the memory card (alongside the videos). Later during playback on your computer or smartphone, you'll be able to see the vehicle speed and position on a map.

There is no cost or fee whatsoever associated with using passive GPS antennas such as these to record where, when, and how fast your vehicle is going; just plug and play!
