CONGRATULATIONS

Thanks for purchasing the Directed HD Car Connect Radio. This is a unique system
that can integrate with any automotive radio. This device will open the door to all the
hidden digital stations on your radio. Be sure to save your sales receipt. It is your best
record of the date of purchase, which is required for warranty service. Read and follow

High-powered car audio systems may produce sound pressure levels that
exceed the threshold at which hearing loss may result.

They may also impair a driver’s ability to hear traffic sounds or emergency vehicles.
Use common sense and practice safe listening habits when listening to or adjusting
your audio system.

SETUP/INSTALLATION

Mounting the Commander module:

The unit comes with 2 brackets. There are two holes located on each
side of the unit that allow the 4 screws the unit comes with to hold the brackets
into place. The module is small enough to be mounted under a seat, in the trunk,
or possibly behind the dash depending on the vehicle. Avoid mounting near any
movable parts, places where there can be moisture, near high temperatures, or
areas that are susceptible to electric interference. Be sure the unit has proper venti­lation. For example a rear seat in a car may not have enough space for proper air
circulation.

RED = +12 VOLTS SWITCHED
YELLOW = + 12 VOLTS CONSTANT
BLACK = GROUND

OUT

Power Harness:

Yellow - +12 volt constant. This wire should show 12 volts regardless of the posi-

tion the key is turned to in the ignition. It is located in the top right pin of the 4 pin
connector plug.

Note: If your sound system is set up with remote
amplifiers or line inputs the audio outputs can be con­nected directly to you system with RCA cables from
these Audio Output jacks.

Red - +12 volts switched. This would be hooked to a wire that shows +12 volts
when the key is turned to the accessory or run positions but not show voltage when
the key is in the start position. This is the wire that tells the unit to turn on and off.
It is located in the lower right pin of the 4 pin connector plug.
Black - Ground. This should be connected to a chassis ground. This should be a
paint free surface. A good example is the kick panel. This wire is located in the top
left pin of the 4 pin connector.

Antenna In:

This is what allows the Car Connect to receive radio signals. The unit comes with an
antenna cable that has 1 male connector and 1 female connector on opposite ends
in order to extend the factory antenna wire. It may require the use of an antenna
adapter depending on what kind of vehicle it is being installed into.

Antenna Out:

This will allow the antenna to pass through to the radio's receiver. The unit comes
with an extension cable with 2 male connectors. One lead goes to the Car Connect,
the other goes to the antenna input for the car radio. This would still be required to
be installed even if using the RCA output, otherwise the head unit's tuner would not
be able to get reception anymore. This also allows for the fm modulator to output
signal through the selected radio station for radio's that do not have an auxiliary
input.

Audio output:

If the Car Connect is being installed in conjunction with a radio that has an auxiliary
input, the RCA output can be used. White is for the left signal and red is for the right
signal. This is not necessary to be installed if the desired output is through the fm
modulator only.

Interface:

The display connects on the 8 pin interface port located right on the main unit. The
display should be mounted in an area that makes it easily accessible. This could be
a center console area. The interface may be mounted with a double sided adhesive
such as Velcro or tape. Be sure the area is cleaned thoroughly first. Then apply the
adhesive.

Loss of signal strength while playing HD
a. If stream does not resume within 10 sec,
Switches to analog signal (does not mute even if analog signal is

poor).
Flashes the "Blinking HD logo" screen overlay for 10 seconds.
Removes HD logo and updates display to analog signal type.
b. If stream resume within 10 sec,
Maintains previous SPS channel and display mode.
Discontinued supplementary channel while playing HD
If an HD supplementary channel is discontinued while the unit is tuned to it,

RADIO DATA SYSTEM (RDS) MODE

Note: RDS (Radio Data System): This technology allows stations to transmit additional
types of information via encoded digital signals that can be received and displayed by the
user's Radio. For instance: an RDS-capable Radio can display the title and artist or current
song playing, local traffic information, an advertiser's phone number while a commercial
is playing, etc.

When RDS data was received, the display is changed as below automatically. The display
in RDS Mode has two types of Display Mode.

In Display Mode 1, Station name and Radio text information on separate lines are
displayed. And the preset indicator, Seek indicator, band, frequency, RDS logo and Signal
strength bars are displayed on Status Line.
