I have Garmin Taiwan Topo 6.0.2 map, (includes 600 mountain trails)
When I browser the map,
I found the mountain trails only display below 300m(meter) ZoomIn level,
That is, I cannot see the trails at 1000m ZoomIn level.

Is there any way to modify the map to show the trails at at 1000m ZoomIn level ?

If that is possible, that would be very help for hiking.
Thank you very much.
