2.1 General
GNAD1A is a proprietary GSM/GPRS/EDGE module from Continental Automotive Systems.
The module will be integrated into telecommunication control devices produced by Continental
for its automotive customers.
The GAND1A test set-up is available for third-party testing which do not require audio or data-
logging capabilities. This document will provide description for the test set-up.
