The C5 Cellular device allows a direct GSM connection with a user supplied SIM card. The device also has it’s own built in GPS receiver (Telit HE910). The C5 Cellular does not plug directly into the OBD-II port, but instead has an OBD-II to DB9 cable to allow placement of the device or good reception as well as the ability to put the larger device out of the way.
