This gadget has no internal battery, so it turns off immediately with ignition-off. It does not turn on directly when power is back (ignition-on), you have to push the button for two seconds to turn on the device. Therfore, the location of the device as shown in the picture is ideal. From booting the device to active nav-connection is about 30-40 seconds, but I think it can strongly vary per location and or service provider. In this connection time testing, the device went from red to green (4G connected), red again (no connection) to green again and then the car nav gave the message "wifi connected", all within about 35 seconds.
On the road, I sometimes see the light going from green (4G) to orange (3G or lower) and back to green again.
