GPS receiver to enable your iphone or android to determine position when out of mobile cell range. Such uses could be marine, aviation or extreme terrain. Uses GPS/GLONASS and will only receive ‘line of sight’ signals, so will not work underground or even indoors if the receiver cannot ‘see’ the satellite constellation. Tested and working 17/7/25 Does not include mounting pad - only car charger, usb charger, instructions and receiver
