Installation
1. When making electrical connections it is always recommended that
the vehicle’sbattery be disconnected from the electrical system before
performing the installation.
Please Note: If the radio is equipped with a built in CD
Changer, please remove ALL discs before proceeding to
prevent damage to the radio’s CD mechanism.
2. Carefully remove the trim panels covering the bolts that secure the
radio into the dash cavity. Remove these bolts, and carefully pull the radio
from the dashof the vehicle. This will provide access to the factory radio
connectors where youwill connect the vehicle specific harness.
3. Disconnect the factory harness (if present) from the back of the radio. If
you are installing the PXAUX into a Toyota or Honda with an external CD
Changer and you are using CD Changer emulation mode, the CD
Changer will have to be disconnected at the changer location for proper
operation.
4. Connect the 8-Pin auxiliary input cables to the ports on the PXAUX
5. Plug in the male connectors on the vehicle specific harness into the port
on the back of the radio. Next, connect the factory harness (if present)
into the female connector on the vehicle specific harness. Be sure to
make a firm connection but do not force it. Plug the Black micro-fit 24-pin
connector on the vehicle specific harness into the PXAUX.
6. To complete the installation secure the PXAUX into the cavity in the dash
behind the radio. Be sure that the cables and interface modules are not
near moving parts or sharp metal edges as they may damage the cables.
To prevent rattling noises inside the dash, use zip ties, tape, or other
fasteners to mount the interfaces securely.
7. With all connections made, reconnect the vehicle’s battery, insert the key
into the ignition, and turn the vehicle on. Check for proper operation of the
PXAUX before reinstalling the factory dash panels.
8. Note: The first time you access the PXAUX, your radio may display “DEV
INIT” while the device is initializing. If this is displayed, please wait one
minute then cycle the ignition off and on. Then access PXAUX mode
again to begin normal operation.
