Location & Time
The Location & Time menu displays GPS navigation information as well as the current
system time and date. This menu also allows the GPS, time, and date information to be
changed. An example of the Location & Time menu is displayed in figure 16.
Figure 16. Location & Time Menu Display
As shown in figure 16, Both GPS and system time are displayed. The top of the display
details current GPS navigation system status. The GPS status indicator may one of three
statuses:
No Response: This indicates that there is no data being received from the GPS
receiver by the MMI.
No Position: This indicates that the MMI is receiving data from the GPS receiver,
but there are not enough satellites in view to navigate with.
Active: This is the normal status indication that the MMI is receiving data from
the GPS receiver, and the receiver is producing good Lat/Lon position
data.
The next lines on the display show the current system date as well as both system and
GPS time. The GPS UTC time is in a format known as universal time coordinated (UTC)
which is a world-wide time. Depending on the location in the U.S., UTC time is a few
hours ahead of local time. UTC time is extremely accurate, as it is derived from atomic
clocks abord the GPS satellites.
