INSTALLATION
This unit is designed for installation in vehicle cabs with an existing 1-DIN radio opening. In 
many cases, a special installation kit will be required to mount the radio to the dashboard. See 
the dealer where the radio was purchased for kit availability. Always check the kit application 
before purchasing to make sure the kit works with your vehicle.
Before You Begin
1.
Disconnect Battery
Before you begin, always disconnect the battery negative terminal.
2.
Remove Transport Screws 
Important Notes
Before final installation, test the wiring connections to make sure the unit is connected 
properly and the system works.
Use only the parts included with the unit to ensure proper installation. The use of 
unauthorized parts can cause malfunctions.
Consult with your nearest dealer if installation requires the drilling of holes or other 
modifications to your vehicle.
Install the unit where it does not interfere with driving and cannot injure passengers during 
a sudden or emergency stop.
If the installation angle exceeds 30º from horizontal, the unit might not give optimum 
performance.
Avoid installing the unit where it will be subject 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 chas-
sis 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 3.
2.
Check the dashboard opening size by 
sliding the mounting sleeve into it. If the 
opening is not large enough, carefully cut 
or file 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 
perforated strap to a 
secure part 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 
the radio.
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.
Removing the Unit
To remove the radio after 
installation, remove the plastic end 
caps, insert the removal keys 
straight back until they click, and 
then pull the radio out. If removal 
keys are inserted at an angle, they 
will not lock properly to release the 
unit.
Reconnect Battery
When wiring is complete, reconnect 
the battery negative terminal.
