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

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.

INSTALLATION INSTRUCTIONS
STEP 3: Mount InfiniMount Shafts to Brackets
To match the location of your shafts to the proper width of your
vehicle’s dash, rst measure the distance between your existing shaft
holes from center to center.
Mount a shaft to each bracket using the supplied shaft nuts
and washers. Finger tighten the shaft nuts to prepare for the nal
installation (See Figure 3). Once you ensure proper width, tighten
the screws and nuts (DO NOT OVERTIGHTEN).
DAMAGE FROM OVERTIGHTENING WILL VOID YOUR WARRANTY.
Finally, plug the shafts into each side of the main unit (See Figure 4).

NOTE: Cutting the wiring harness, antenna lead or auxiliary cable
will void your warranty.
STEP 4: Complete Wiring Connections

12
NOTE: This unit requires +12 volts to both the red and yellow wires to operate properly.
Locate the three wire harnesses: main wire harness, power wire
harness and speaker wire harness (See “What’s in the Box”
on page 4). First connect the main wire harness to the back
of the radio. Then connect both the power and speaker wire
harnesses to the black female plug of the main wire harness.
After doing this, connect the bare wire ends of your power and
speaker wires to the appropriate power and speaker locations in your
vehicle (See Figure 5). Have your radio installed by a professional if this
part of the install is too difcult, or contact us if you have questions.
Installation Notes
• To prevent damage to the unit, do not connect the power
connector until you have completed the wiring process.
• This is a 12 volt negative ground ONLY radio. If you
have a positive ground, or a 6 volt system, you need
to either convert to 12 volts or purchase a separate
inverter that would increase the voltage to 12 volts.
• Please note that any inverter must be rated at 8 amps
or higher in order for the radio to operate properly.
Rear AUX Inputs
Two AUX inputs are located at the rear of the Motor 1 radio body.
These auxiliary inputs allow you to listen to any external source with
a standard headphone output. An example of an external source
would be a MP3 player, iPod®or iPhone®, portable CD player
or portable satellite radio receiver. To use this input, the auxiliary
cable must be routed to an accessible area during installation.
INSTALLATION INSTRUCTIONS

INSTALLATION INSTRUCTIONS
Rear USB Input
A USB connector cable is located at the rear of the Motor 1 radio
body. During installation, you must route the cable to a convenient
and accessible location for plugging in USB devices. If the cable
provided is not long enough (40 inches), you may use our optional
USB/AUX Extension Cable to extend the reach of the cable. This
cable also allows you to install the USB/AUX port into the factory
location for the cigarette lighter for a factory look and easy access.
STEP 5: Finish the Installation
IF USING A BEZEL, Place the bezel on the face of the radio. Install the
assembled radio from behind the dash until the bezel and radio face
are ush with the front of the dash and the radio shafts protrude through
the shaft openings in the dash. Using the supplied washers and shaft
nuts (see “What’s In the Box” on page 4), secure the radio to the dash.
IF USING A FACEPLATE, slide the radio into the hole from behind the
dash, then align the faceplate over the radio shafts from the front.
Using the supplied washers and shaft nuts (see “What’s In the Box” on
page 4), secure the faceplate to the dash and the radio.
DAMAGE RESULTING FROM OVERTIGHTENING THE SHAFT NUTS
WILL VOID YOUR WARRANTY.
Finally, you’ll need to secure the rear of the radio using the supplied
back strap and hardware (See “What’s in the Box” on page 4). The
back strap mounts using the threads in the rear of the radio body and
can be bent and adjusted to align with the mounting point of the
original factory radio behind the dash. Now you can install your knobs
by placing them onto the shafts.
