3.6. GPS Module
A GPS module can be positioned in the first or second slot of optional modules, see section Section 3.11,
“View of Radio Modem”. (For MG100 only in the first slot.) The second slot is recommended because
when using slot 1 you first need to disconnect it in the modem´s service mode, see section Section 3.10,
“Service Connector”. You can find further detailed information on the module manufacturer’s web
