What is the difference between GTN 750 and GTN 750Xi?
High-speed processors cut boot-up time by 50% over earlier GTN models. And with almost double the pixel count of its predecessor, the GTN Xi series features wider viewing angles and one of the highest-resolution displays ever offered in this class of avionics. The GTN Xi has an updated IPS LCD screen, which upgrades the resolution from 134 DPI to 187 DPI. It has a more modern look than the original GTN did. The location of the buttons on the GTN Xi was moved closer to the bottom right knob. The GTN Xi has a dual processor, which makes it a lot faster than the original GTN.
