The cards once were charge and placed on my car was not what I was expecting. I send my car for a cleaning detail and placed the card in my glove compartment. From the moment my car moved I followed it. Never moved or at least took a while to be recognized to let me know were it was. Eventually the signal let me know but the location was not accurate. I compared it with the location on my truck from the Ford app that was on spot. I will check again when I drive to a mall how I find it .
