Igo NextGen Version: iGO_Navigation_9.18.27.682862

Screen resolution: 480 x 234

1) How can I get the horizon to be displayed i.e. show a bit of sky! My 3D is almost 2D on the screen.

Also,

2) When I join the motorway the view zooms out so far that all the icons disappear, how can I reduce the amount by which this happens?

Thanks,
