Insert one end of the SmartBus cable into the “DATA BUS” slot on the side of the 

NAV104 and secure it with an 11 mm ( 0.4 in ) screw (provided). Connect the other end 

of the cable to the NAV104 input on the back of your Jensen navigation-ready  

head unit. 

Some compatible head units have a cable-to-cable 

connection and do not require an anchor screw.

Where applicable, secure the cable to the 

radio using an 11 mm ( 0.4 in ) screw.

Attach the 

GPS Antenna 

to the 

“ANTENNA” 

jack on the 

side of the 

NAV104.

Insert the SD Card into the SD Card Slot and gently 

press the card in against the spring latch until it 

stops, then release. The card will “lock” firmly into 

place inside the SD Card Slot.
