Specialist words
ETA
((Estimated Time of Arrival)
The estimated time of arrival at the des-
tination. When making calculations, the
Traffic Assist Pro takes into considera-
tion the various average speeds for dif-
ferent road types (inner city, A-roads,
motorways, etc.) and the current traffic
situation in combination with the TMC.
GMT
(Greenwich Mean Time)
Central European Time
The standard time at 0 degrees of longi-
tude (the longitude which passes
through Greenwich, Great Britain). This
time is used worldwide for the synchro-
nisation of data collection.
GPS
(Global Positioning System)
GPS determines your actual geographi-
cal position by the use of satellites. It is
based on 24 satellites which orbit the
Earth and emit signals. The GPS receiv-
er receives these signals and calculates
the distance to each satellite from the
running time differences and thus evalu-
ates its actual current position in terms
of geographical length and width. In or-
der to determine the position, signals
from at least three satellites are required,
and the fourth one allows the height to
be determined.
HDOP
(Horizontal Dilution Of Precision)
HDOP states the quality of the positional
dtermination. In theory, values from 0 to
50 are possible, whereby the following
applies: the smaller the value the more
accurate the positioning (value 0= no de-
viation from the actual position). Values
of up to 8 are acceptable for navigation
units.
ID3-Tag
„Index of Contents" of an MP3 title.
Contains information such as title, artist,
album, year and genre.
JPG/JPEG
(Joint Photographic Experts Group)
The JPEG is the most common type
of storage format for dissipating picture
compression., i.e. when compressing,
details of the picture are lost. Still pro-
vides good picture quality despite com-
pression, compression stages are se-
lectable. It is the most common format
for representation and exchange of pic-
tures on the internet.
MP3
Special compression process for audio
data (e.g. music).
File
Index
File on a CD/storage card/microdrive
which contains MPS titles.
SD Card
(Secure Digital)
The Secure Digital Card was developed
in 2001 by SanDisk on the basis of
the older MMC standard. An SD card is
a re-writable change-over storage card.
