INSTALLING AND MOUNTING THE GPS UNIT 

The GPS unit will work best if it has a clear view of the sky and as much of the 
horizon as possible with no metal between it and the sky. Any metallic objects 
between the GPS unit and the satellites will degrade the signal and reduce the 
overall performance.  For best signal acquisition, the roof of the trailer is the 
recommended mounting position. (This will require extending the wires on the 
unit to reach your trailer wiring socket or refer unit battery.)  You can also mount 
the device on the front of the trailer as pictured below.  For refrigerated trailers 
the device can be mounted inside the refer shroud (as long as it is plastic or 
fiberglass) and you can use the refer units battery for the external power source. 
   

WARNING Any metal structure can affect the accuracy of the GPS signals and 

prevent normal operation. Location of the GPS unit is critical to the operation. 

 
The GPS unit can be installed on 
any type of vehicle. The unit should 
be mounted so it will not be exposed 
to damage from people or objects. 
The GPS unit has tabs for mounting 
screws or you can use epoxy or 
double sided tape to attach the unit 
to your trailer.
