Select an appropriately sized location for the unit.
Use the Flush Mount Template provided to determine a location.
Check that all cables reach the unit mounting location.
Always wear safety goggles and a dust mask when drilling, cutting, or sanding.
Included mounting hardware—(1) unit housing, (1) rubber seal, (2) tension mount brackets, (4) hex bolts, (4) hex nuts, and (4) wing nuts.
Tools (not included)—drill,

(10 mm) drill bit, jig saw, and a

(7 mm) wrench.
To install the Flush Mount Kit:
1. Cuttheopening:
The flush mount template has adhesive on the back. Remove the protective liner and apply the template to the location you want to
mount the unit.
Using a
3
/
8
" (10 mm) drill bit, drill the pilot holes indicated on the template to begin cutting the mounting surface.
Using the jig saw, cut the mounting surface along the inside of the line indicated on the template. Be very careful when cutting this
hole, because there is only a small amount of clearance between the unit housing and the tension mount arms. Cut slightly inside the
indicated line and then sand or file the panel as needed to obtain the best fit.
2. Assemble the flush mount hardware (see Figure 1):
Attach the rubber seal to the front of the unit housing.
Insert the four hex bolts into the unit housing so they stick out of the back.
Use the four hex nuts to secure the hex bolts to the unit housing. Using the
9
/
32
" (7 mm) wrench, tighten the nuts without
overtightening.
Slide the unit into the unit housing. (If you have limited space behind the mounting surface, this can be done in step 3.)
When the unit is inserted correctly, it will snap into place within the unit housing.
Connect the wiring harness, GPS antenna, and XM antenna (if applicable) to the unit. (This can also be done in step 3, if necessary.)
