Here we have people who are realy experts and perhaps will guide you better but for the moment I suggest you my way.
Obviously it depends on the NextGen version you're using, what I say applies to 9.18.27.702387_iGO_World with no others ux than original

The answer
Spoiler: Here

The file who is managing the zoom is data.zip \ ui_nextgen \ common \ skincgf.ini

Specifically, there are six sections, the first is for the horizontal position of the phone and the second for the vertical

"camera1" i "camera11" are for setting: settings/Navigation Map/Map Display/Viewpoint/Close
"camera2" i "camera21" are for setting: settings/Navigation Map/Map Display/Viewpoint/Normal
"camera3" i "camera31" are for setting: settings/Navigation Map/Map Display/Viewpoint/Far

Here are the values ​​we want, my "camera 1" include:
[camera1]
maxdistance=350
minzoom2d=70
defaultzoom2d=80
maxzoom2d=80
overview_zoom2d=3600
minzoom=20
defaultzoom3d=30
maxzoom=40
minangle=55
defaultangle=65
maxangle=75
angleoffset=55
speedzoom=1
speedangle=1
overview_enabled=1
overview_distance=3000
overview_zoom3d=800
overview_angle=75

The angles are measured in degrees from the vertical so the larger the angle is more horizontal viewing


I hope I have helped you. If in doubt ask.
