Tina,
Yes, the GPS will give you information based on relative heading. There are
three Heading Orientations: Left/Right, where direction is presented by
Ahead, Slight Right, Right, Behind Slight Right, Behind, Behind Slight Left,
Left and Slight Left; Clock-Face, where direction is presented by 12, 1, 2,
3, 4, 5, 6, 7, 8, 9, 10 and 11 o'clock; Both Left/RIght and Clock-Face,
where direction is provided with Ahead, 1 and 2 o'clock, RIght, 4 and 5
o'clock, Behind, 7 and 8 o'clock, Left, 10 and 11 o'clock.
The important thing with the heading is to make sure that you are moving in
a constant direction or have moved in a constant direction before asking for
information. For example, it probably isn't a good idea to ask for things
after just turning or spinning in a few circles. If you were to be heading
down the street and you were going North and made a right by pivoting, the
GPS still thinks that you are facing North, it will be required that you
move in a constant direction for about 30 second before a reliable heading
can be given.
Thanks,
Kevin

Well, I ordered it today and can't wait for Tuesday when it gets here! I was
just wondering, when I plan a route or am out walking around, does it havet
o give you information in terms of north south, etc, I do have a compass,
but think more easily in terms of left and right, so, can it give me info
that way such as this or that place is on the right or left side of the
street or tell me that I am on that side of the street?
