OUNTING THE 
DVR  
Note: The DVR can be mounted in various orientations 
(except upside down), but you must leave enough space 
to pull the latch and remove the HDD.  
See Figure 21 and perform the following: 
1)  Mount the mounting plate (
) to the 
vehicle using four nuts and bolts (not 
provided) (1/4-20-inch bolts (
) are 
recommended). 
2)  Remove the four acorn nuts (
) and 
locking washers (
) from the top of the 
vibration isolators (
) (Do not remove 
the vibration isolators (
) or the bolts 
and nuts holding them in place.) 
3)  Place the DVR outer housing (
) back 
onto the mounting plate by lining up the 
holes in the mounting brackets (
) with 
the bolts in the vibration isolators. 
4)  Reattach the four acorn nuts and locking 
washers.
