Avoid installing the unit where it will be subjected to 
high temperatures from direct sunlight, hot air, or from a 
heater, or subject to excessive dust, dirt or vibration.

DIN Front Mount

1.   Slide the mounting sleeve off of the chassis if it has not 

already been removed. If it is locked into position, use 

the removal 

keys (supplied) 

to disengage it. 

The removal keys 

are depicted in 

“Removing the 

Unit” on page 6 . 

 

2.   Check  the 

dashboard 

opening size 

by sliding the 

mounting sleeve into it. If the opening is not large 

enough, carefully cut or files as necessary until the sleeve 

easily slides into the opening. Do not force the sleeve into 

the opening or cause it to bend or bow. Check that there 

will be sufficient space behind the dashboard for the radio 

chassis. 

3.   Locate the series of bend tabs along the top, bottom and 

sides of the mounting sleeve. With the sleeve fully inserted 

into the dashboard opening, bend as many of the tabs 

outward as necessary to firmly secure the sleeve to the 

dashboard. 

4.   Place the radio in front of the dashboard opening so the 

wiring can be brought through the mounting sleeve.  

5.   Follow the wiring diagram carefully and make certain 

all connections are secure and insulated with crimp 

connectors or electrical tape to ensure proper operation.  

6.   After completing the wiring connections, turn the unit 

on to confirm operation (vehicle accessory switch must 

be on). If the unit does not operate, recheck all wiring 

until the problem is corrected. Once proper operation is 

achieved, turn the accessory switch off and proceed with 

final mounting of the chassis.  

7.   Carefully slide the radio into the mounting sleeve making 

sure it is right-side-up until it is fully seated and the spring 

clips lock it into place.  

8.   Attach one end of the perforated support strap (supplied) 

to the screw stud on the rear of the chassis using the hex 

nut provided. Fasten the other end of the dashboard 

either above or below the radio using the screw and plain 

washer provided. Bend the strap, as necessary, to position 

it. Some vehicle installations provide cavity for rear 

support. In these applications, place the rubber bushing 

over the screw stud and insert. 

CAUTION: The perforated rear support strap or rear rubber 
mounting bushing must be used in the installation of the 
radio. Installation without either may result in damage to the 
radio or the mounting surface and void the manufacturer’s 
warranty.

 

9.   Test radio operation by referring to the operating 

instructions for the unit.
