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 specic 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 specic harness into the port

on the back of the radio. Next, connect the factory harness (if present)

into the female connector on the vehicle specic harness. Be sure to
make a rm connection but do not force it. Plug the Black micro-t 24-pin
connector on the vehicle specic 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 rst 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.

Instructions for Correcting the

Loss of Factory XM Radio

When Using the PGHHD1 Harness

It has come to our attention that the factory XM radio tuner becomes inoperable when using certain PGHHD1
harnesses with the GateWay, DuaLink or Connect interfaces. This is caused by an error in the manufacturing of
the harness. The problem can be resolved in the eld by following the procedure outlined in this tech brief.

1. Locate the two org/blk wires which are in
pins 19 & 7 of the 24-pin connector. You
will need to reverse these two wires to
correct the problem.

2. Remove the tape from the harness to gain
better access to the two org/blk wires.

3. Cut one of the org/blk wires below

the heat shrink. After you have cut
this wire, mark each side with
electrical tape or zip ties to ensure
you recconnect the wires properly.

4. Cut the second wire and

reconnect both wires in
reverse order. When done
it should look like the picture
on the far right.

5. Solder & insulate all connections.

Re-install into the vehicle. You’re

Reset Procedure

** MODULE MUST BE DISCONNECTED FROM THE VEHICLE BEFORE PERFORMING THE FOLLOWING STEPS **

1. With a #1 Philip head screwdriver remove the two screws on the bottom of the module and
remove the circuit board from the housing.

2. Locate the 24 Pin connector that plugs into the vehicle specific harness, next to it you will
see a bank of nine capacitors.

3. Within the group of nine capacitors there will be one that is larger than the rest and have a “+”
symbol on the top of it. (see Fig. 1)

4. Flip the module over and find the two leads from that capacitor. (see Fig. 2)

** MODULE MUST BE DISCONNECTED FROM THE VEHICLE BEFORE PERFORMING THE FOLLOWING STEPS **

5. Take your screw driver or any other metal object and touch these two leads together temporarily
to drain the residual voltage from this capacitor.

6. Place module back into the housing and secure the housing back together using the screws
that were removed in Step #1.

7. Install module back into vehicle ensuring that the iPod or other accessories are connected to the
module prior to plugging the module into the vehicle.
