MY NAVIGATION OFTEN GOES BLANK WHEN PASSING TREES OR THE SIDES OF BUILDINGS.
I HAVE HAD A GARMIN FOR YEARS AND WAS ABLE TO ADD AN ANTENA TO THE GARMIN WHICH COMPLETELY TOOK CARE OF THE PROBLEM.

DOES ANYONE HAVE ANY EXPERIENCE OR ANSWER ABOUT THIS PROBLEM?

THANKS,

The question is; "Is your system equipped with a Gyro?" Reason for asking is because the gyro will maintain the heading or last information plotted until you get back into the open or away from what obstructs your satellite signal.
