Frequently Asked Questions General What is the difference between degrees/minutes/seconds (DEG/MIN/SEC) and degrees/minutes/minutes (DEG/MIN/MMM or DEG/MIN/MM)? There are different ways in expressing the coordinates computed using Lat/Lon coordinate system. With DEG/MIN/SEC the final set of numbers (SEC) is expressed as 0-59 while DEG/ MIN/MM expresses the same value as 0-99 and DEG/MIN/ MMM is from 0-999. It would be the same as if you had one clock that expressed time as hour/minutes/seconds and another clock that expressed the same time as hours/minutes/decimals. The accuracy for any of the three is the same. Which you choose is dependent upon your preference or any chart you are using at the same time. (You should always make sure that your MAP 330 is setup to be the same as any map or chart you may be using.) What is 2D vs. 3D? The difference is primarily how many satellites are used to compute the position fix and how elevation is computed. In 2D (two-dimensional) only three satellites are needed for a position fix and elevation is not computed. Any elevation displayed by the MAP 330 during 2D operation is the elevation you entered. In 3D (three-dimensional), a minimum of four satellites are needed to compute the position and at the same time, elevation is computed by the MAP 330. When the time changes for daylight savings time will the time, in the MAP 330 change automatically? No. The time transmitted by the satellites atomic clock are UTC (Universal Time Coordinated) and provides no correction for daylight savings. When daylight savings time changes (or when you move to a new time zone), you need to go into Setup - 62 Magellan MAP 330 GPS Receiver

Frequently Asked Questions
Frequently Asked Questions
General
What is the difference between degrees/minutes/seconds (DEG/MIN/SEC)
and degrees/minutes/minutes (DEG/MIN/MMM or DEG/MIN/MM)?
There are different ways in expressing the coordinates computed
using Lat/Lon coordinate system.
With DEG/MIN/SEC the
final set of numbers (SEC) is expressed as 0-59 while DEG/
MIN/MM expresses the same value as 0-99
and DEG/MIN/
MMM is from 0-999.
It would be the same as if you had one
clock that expressed time as hour/minutes/seconds and another
clock that expressed the same time as hours/minutes/decimals.
The accuracy for any of the three is the same.
Which you
choose is dependent upon your preference or any chart you are
using at the same time.
(You should always make sure that your
MAP 330 is setup to be the same as any map or chart you may
be using.)
What is 2D vs. 3D?
The difference is primarily how many satellites are used to
compute the position fix and how elevation is computed.
In 2D
(two-dimensional) only three satellites are needed for a position
fix and elevation is not computed.
Any elevation displayed by
the MAP 330 during 2D operation is the elevation you entered.
In 3D (three-dimensional), a minimum of four satellites are
needed to compute the position and at the same time, elevation
is computed by the MAP 330.
When the time changes for daylight savings time will the time, in the MAP
330 change automatically?
No.
The time transmitted by the satellites atomic clock are UTC
(Universal Time Coordinated) and provides no correction for
daylight savings.
When daylight savings time changes (or when
you move to a new time zone), you need to go into Setup —
