INSTALLATION
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 vessel.
Install the unit where it does not interfere with driving and cannot injure passengers if 
there is a sudden or emergency stop.
If the installation angle exceeds 30º from horizontal, the unit might not give optimum 
performance.
This unit is not waterproof and is intended for interior mounting applications only. 
Exterior mounting of the unit requires use of an ASA approved marine housing.
Avoid installing the unit where it will be subject to high temperatures from direct sunlight, 
hot air, or from a heater, or where it would be 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 (vessel 
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 and spring washer 
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. CAUTION: The rear of the 
radio must be supported with 
the strap to prevent damage to 
the dashboard from the weight 
of the radio or improper 
operation due to vibration.
9.
Test radio operation by referring to the operating instructions for the unit.
Removing the Unit
To remove the radio after installation, pull back 
the rubber covers, 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.
