CHAPTER 1: Installation

Make sure the heads are positioned approximately the same height as the 
license plate and separated by at least 24 to 30 inches from each other. Being 
too close together can cause interference. 

Use the included green bubble level tool to make sure the heads are 
horizontally positioned, and are facing straight forward, and ensure all torque 
screws are tight.

When using a third head, install the head in the center of both heads,  
below the car’s emblem or directly above the license plate.

The CPU computer has a capability of having 8 heads total
with an optional splitter. 

Make sure 
transponders  
are facing 
straight forward.

Make sure the heads are 
horizontally installed by using 
the bubble level included in 
the package.

Changing the Lens cover

After a year of use on the road, replace 
the old lens cover with a new one. Use 
a pin to pry open the old lens cover to 
replace it.

Cables

Arrows on cable align for 
proper fit. 

Optional third head for maximum protection.

BMW owners have the option to install the heads vertically. However a third  
horizontal head is required so you have two vertical outside heads and one center 
horizontal head.
