※ The GSM antenna comes in two parts. They must be firmly screwed together to receive a strong signal. This antenna is not all weather but it can receive a
signal through metal. A good position for this antenna is to run the wiring behind the corner post of the vehicle and locate the antenna in the hood lining
behind the sun visor. Once again only screw wiring to device by hand as damage could be caused by the use of a spanner.
Connect the GPS antenna to EV604.
※ The GPS antenna is an all weather unit and is magnetized for easy attachment.
※ The signal for the GPS cannot penetrate steel, only plastic so the GPS antenna must be located in an open position. The best location is under the plastic
