These instructions MUST be used with template part number 988-
0154-691, which accompanies this instruction sheet. Please read all 

instructions before proceeding. NOTE: Recommended tools for this job 

include: jig saw, drill, 1-3/4" (44.45 mm) hole saw, 1/8" (3.18 mm) drill 
bit, Phillips head screwdriver and adjustable wrench. 
1. Select the desired mounting location. Make sure there is enough room 

behind the dash to attach the power, network, antenna and/or trans-
ducer cables. The case with cables attached is approximately 4.50" (114.3 

mm) deep behind the mounting surface. The maximum dash thick-
ness that can be used with this mounting kit is 1" (25.4 mm). Care-

fully measure the dash thickness before cutting any holes. 
2. Tape the template supplied with these instructions to the dash. Be-
gin the cutout by drilling four 1-3/4" (44.45 mm) holes inside the cutout 

to accommodate the saw blade. Use the 1/8" (3.18 mm) drill bit to drill 
the four mounting screw holes where indicated on the template.  
3. Slip your saw blade into one of the 1-3/4" (44.45 mm) starter holes 

and then saw along the indicated cutout line. Be careful when working 
around the corners, because there is little room for error. 
4. If the installation location is exposed to weather, you may want to 

seal the cutout. If that's the case, before you place the unit into the 
opening, apply a bead of RTV silicone or other suitable sealant to the 

back of the unit. In addition to the outside edge, be sure to apply seal-

ant around the four mounting screw holes, as shown in the following 
figure. 
5. For each of the four screws provided, thread a lock nut and flat 

washer onto the shaft to create a total of four screw assemblies as 
shown in the second image. 
6. Place the unit into the dash cutout. (If space is cramped, it's usually 
easier to connect the cables before placing the unit in the dash.)
