PRECAUTIONS
PLEASE OBSERVE THESE PRECAUTIONS WHEN INSTALLING
AND USING THIS UNIT:
This user’s manual does not cover all possible installation scenarios.
If you feel you can’t install this unit yourself, take it to a local car
audio professional. If you have questions about installing your
radio, contact us at [email protected] or call us
at 888.325.1555.
• Do not disassemble or modify the unit or attempt to
repair the unit yourself. If the unit needs to be repaired,
consult your dealer or Retro Manufacturing, LLC.
• Do not use the unit when it is out of order. If the unit is out of
order or is in an abnormal state (has foreign objects in it, is
exposed to water, is smoking or smells), turn it off immediately
and consult your dealer or Retro Manufacturing, LLC.
• Refer fuse replacement to qualied service personnel.
When the fuse blows, eliminate the cause and have it
replaced by a qualied service technician with the fuse
prescribed for this unit. Incorrect replacement of the fuse
may lead to smoke, re and damage to the unit.
• If the unit does not turn on, check the connections rst. Then
check the fuse in your vehicle’s fuse box and the fuse at
the unit’s wiring harness. Do not expose the unit to direct
sunlight or excessive heat. Excessive heat will raise the
interior temperature of the unit, which may damage it.
• Do not use the unit where it is exposed to moisture or dust.
Exposure of the unit to moisture or dust may lead to smoke, re
or other damage to the unit and will void your warranty. Make
sure the unit does not get wet in car washes or on rainy days.

PRECAUTIONS
• Refer wiring and installation to qualied service personnel.
Installation of this unit requires special skills and experience.
For maximum safety, have it installed by your dealer or
qualied service professional. Retro Manufacturing, LLC
is not liable for any problems resulting from improper
installation of the unit. Please be sure to follow the
instructions carefully while attempting installation.
• Follow instructions to wire the unit. Failure to follow the instructions
could cause damage to the unit, re, injury or death.
• Be careful not to damage the leads. Prevent them from
being caught in the vehicle chassis or from being damaged
by screws or moving parts such as seat rails. Do not scratch,
pull, bend or twist the leads. Do not install them near heat
sources or place heavy objects on them. If leads must
be routed around sharp metal edges, protect them by
wrapping them with vinyl tape or similar protections.
NOTE: Cutting the main wire harness, antenna lead, USB cable or auxiliary cables
will void the warranty of your radio.
• Use the designated parts and appropriate tools
to install this unit. The use of parts other than those
supplied may result in internal damage to the unit.
• Do not interfere with safety-related vehicle components.
Do not wire or afx this unit to the fuel tank, brakes,
suspension, steering wheel, pedals, etc. Check for electric
wiring, piping and other items before installing the unit.
• Never install the unit in a location where it
interferes with your eld of vision.

PRECAUTIONS
• Never splice into the power lead to supply
other equipment with power.
• After installation and wiring, always check the normal
operation of other electrical equipment.
• Make sure that no wires interfere with driving
or getting in and out of the vehicle.
• Insulate all exposed wires to prevent short-circuiting or electric shock.
• Do not operate the unit for prolonged periods
with the engine off. Prolonged operation with the
engine turned off will drain the battery.
• To prevent accidents, keep the volume of your radio at a level
that allows you to hear outside noises such as emergency
sirens and train crossing warnings. Prolonged exposure
to high volume levels may also result in hearing loss.
• This unit requires 12 volts to both the red and yellow power leads.
The unit will not work without power to both of these leads.
• Disconnect the negative (-) battery cable before beginning
installation. Verify the battery ground by checking that one
wire is connected to the vehicle’s starter mounting bolt or
engine block and the other to the vehicle’s chassis using at
least 8 gauge wire. Make sure the alternator or generator
connections are secure and free from corrosion, rust or dirt.
• This unit is designed for operation with a negative ground
12 volt DC battery system. Do not operate this unit with
other battery systems, especially an 18 or 24 volt DC or a
positive ground system. If you have a 6 volt system, you
need to either convert to 12 volt DC or purchase a separate
inverter that would increase the voltage to 12 volts.
NOTE: The inverter needs to be rated at 8 amps or higher in order
for the radio to operate properly.

STEP 1: Install the Hermosa Face
Plug the ribbon cable included with the Motor 1 body into
the Hermosa radio face. After plugging in the face, attach
it to the body and tighten with the 4 radio face mounting
screws provided in the radio face box (the screws are very
small and are in the hardware bag with the shaft nuts).
The RetroSound®logo on the Motor 1 body
should be facing upwards. Take care to not
install the face to the body upside down.
NOTE: Optionally, the Hermosa face can be mounted remotely up
to nine feet away from the Motor 1 body using an optional Face to
Body Extension Cable. In some installation applications, a bracket
can be used to mount the face to the body at an angle.

INSTALLATION INSTRUCTIONS
STEP 2: Install InfiniMount Brackets
Attach each InniMount bracket to the correct side of the radio
using the supplied screws. Before tightening the screws, you need
to adjust the brackets up, down, forward or backward. You may
also rotate, cut, or bend the brackets to achieve the perfect t
(See Figure 2). Complete the assembly with at least two screws
tightened on each side.
NOTE: In some installations the brackets must be moved far enough forward or
backwards or rotated so that only two screws will align with the threaded screw holes
on the radio. Two screws are sufcient to hold the brackets in place.
NOTE: You may need to cut, trim or bend the brackets to achieve a perfect t. You
can even drill new mounting holes into the bracket if you need to. The InniMount
system is designed to be modied. Modifying your brackets will NOT void your warranty.
