The GTN Xi navigators provide several improvements over the original GTN navigators including a dual processor and updated LCD screen.

The upgraded processor enables the Xi to be faster than the original GTN. The updated screen improves the resolution from 134 DPI to 187 DPI.

Some of the other minor differences include:

• Location of buttons on the Xi were moved closer to the bottom right knob
• All databases stored internally on the Xi
• The Xi is lighter in weight
• The Xi draws less current
