When this unit is on, control signals are sent
through the blue/white cable. Connect this
cable to the system remote control of an exter-
nal power amp or the vehicle
’
s auto-antenna
relay control terminal (max. 300 mA 12 V DC).
If the vehicle is equipped with a glass anten-
na, connect it to the antenna booster power
supply terminal.
