does the auto day night work for you with the origional navcore for your device running ? as if it does not then it is a hardware issue broken circuit or something, but it is the same for my device witch is a go720 so looks the same as your device if i cover the sensor it does not switch but wait untill night time and it will switch, so please make shure you have the model.txt running x50 emulation and come back when it becomes dark with you. but also check "switch to night colours when dark" is checkd in brightness prefrences.
thanks
