Midwest | I've used a mouse in the USB port of a 20/20 before when the screen was bad. It was the only way to get by until after season when the screen could be replaced.
Why do you need a mouse? I understand a keyboard if you're typing a lot of boundary names I suppose. Seems like a boundary you'd hit start, drive, drive, drive, maybe hit pause and start again, drive drive drive, and finish. Save and name it. 1 down |
