PLEASE OBSERVE THESE PRECAUTIONS WHEN OPERATING
THIS UN IT:
This user’s manual does not cover the installation process. Please review
the Installation and Assembly Manual included in your Radio Motor box

• 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-volt 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 will increase the

• 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.

When a call is incoming, any audio playback from the current source will
either be muted or paused (depending on the source). PHONE IN will be
shown on the screen along with the caller ID if it is enabled by the phone/
carrier. To accept the call, rotate the Left-Rear Knob(2) counterclockwise.
To end the call, rotate the Left-Rear Knob(2) again counterclockwise.
Streaming Music
With a device paired, rotate the Left-Rear Knob(2) clockwise to select BT
AUDIO. Next, select your desired playback source on your device (Apple
Music®, Spotify®, Pandora®, YouTube Music®, etc.) and play the music as
you normally would.
Browsing Music
Some devices will allow you to browse folders and skip songs using the
Right-Front Knob(3) and the Right-Rear Knob(4). To skip songs, rotate
the Right-Front Knob(3). To browse music, rotate the Right-Rear Knob(4)
counterclockwise to access the browsing sub-menu, then rotate the Right-
Front Knob(3) to cycle through the options (artist, album, song, folder) and
press the Right-Front Knob(3) to make your selection.

Frequently Asked Questions
Do your radios work on 6 volt systems or on positive ground sys-
tems?
No. Our radios are 12 volt, negative ground only. After-market converters
and inverters are available but must provide at least 10 amps of continuous
output.
I’m having problems getting the radio to turn on.
RetroSound® radios require 12 volts to both power leads. The red lead
(+12 volt accessory) goes to a switched power source, and the yellow to
a constant +12 volt power source. Using a volt meter, check the voltage
when the key is turned from “off” to “on”. If there is a significant drop in
the voltage, the circuit to which you have the yellow lead attached cannot
handle the additional draw of the radio. You will need to find another
circuit that can handle the additional draw of the radio, or you will need to
go directly to the battery.
What speaker wire do you recommend I use?
We recommend using 16 gauge wire for our speakers.
I have all 4 speakers connected to your radio and the display is lit up
like it is working, but there’s no sound coming out.
This usually indicates one of two things:
• Speaker wires touching each other or the vehicle chassis at some
point. Check each speaker lead from radio to speaker.
• Speaker impedance below 4 ohms. Older speakers are usually
not compatible with modern electronics.
My car originally came with a switch to control my automatic
antenna. Can I use the RetroSound®radio’s remote antenna wire to
control my antenna?
No, you cannot. Your factory antenna is known as “semi-automatic.” It
requires a switch to either extend or retract the antenna. You must retain
this switch to control your antenna; the RetroSound® radio’s power
antenna wire is for more modern “fully-automatic” antennas not requiring
a separate switch.
