NTG4 Hidden Menu Access
Phone Hang-up, #, 1 all at the same time, hold for a few seconds and the hidden engineering menu appears. I needed this to find which map version I had. Be VERY careful about changing anything with this menu unless you are absolutely sure you know what you're doing!!- Chrishazle
