Garmin GPSMAP 175 Owner's Manual page 47

A new waypoint may also be created without knowing position coordinates
by entering its range and bearing from an existing waypoint or your present
position. The GPSMAP 175 will then calculate the position coordinates for
you, using the reference selected.
To create a new waypoint using a reference waypoint:
1. Select the 'Create Waypoint' option from the main menu page and press T.
2. Enter the name, icon and comment for the new waypoint.
3. Highlight the reference waypoint field and press T.
4. Enter the name of the reference waypoint using the R keypad, or press
O to select the waypoint from the nearest list, waypoint list, or map
display. Leave the reference field blank to use your present position.
5. Press T to begin entry of the bearing from your reference waypoint to
the new waypoint position. Enter the bearing and press T.
6. Press T to begin entry of the distance from your reference waypoint to
the new waypoint position. Enter the distance and press T. The position
for the new waypoint will automatically be calculated.
7. Press T to confirm the 'Done' prompt.
A. Enter the bearing
from the reference
waypoint to the new
waypoint in the
'BRG' field.
B. Enter the distance
from the reference
waypoint to the new
