here we have a polar graf on the left side
and two user values
numbers are grayed because we have no signal from GPS
we can switch between speed
VMG, True wind angle, and course
polar can be shown as a quarter with automatic switching to right place
or as a full round. our course is shown by this arrow
also there is two TWD (true wind direction) modes
in manual mode we can alter this value by pressing volume buttons
in automatic mode device tries to guess this direction by analysing polar graph
