Car Stereo System User Manual
5. Installation
1. When making electrical connections it is always recommended that the vehicle’s 
battery be disconnected from the electrical system before performing the installation.
2. Carefully remove the trim panels covering the 8mm bolts that secure the radio into 
the dash cavity. Remove these bolts, and carefully pull the radio from the dash of the 
vehicle. This will provide access to the factory radio connectors where you will
connect the Media Gateway harness.
3.  Disconnect  the  factory  14-Pin  harness  (if  present)  from  the  back  of  the  radio. 
Disconnect the antenna from the radio.
4. Connect the 8-Pin iPod docking cable into the rst  port on  the  Media  Gateway 
(farthest away from dipswitches). Carefully run the 11 foot iPod cable behind the dash 
to the location where the iPod will be mounted or stored (for example the glove box 
or center console). This location will vary based on the vehicle, and the customer’s 
prefrence. When running this cable through the dash be sure to secure it away from 
moving parts or sharp metal edges that may damage the cable. 
5. If connecting the HD Radio Tuner (HDRT sold separartely), make the folllowing 
connections before connecting the PXAMG to the vehichle. Plug the 3 foot HD 
Radio Cable (8-Pin mini-din to 8-Pin mini-din) cable into the second port (closest to 
the dipswitches) on the Media Gateway. Connect the other end of this cable into the 
HD Radio tuner. Connect the factory antenna cable into the antenna connection on 
the HD Radio tuner (HDRT).
6. Plug the male connector on the PGHHD1 harness into the 14-pin port on the back 
of  the  radio.  Next,  connect  the  factory  14-pin  harness  (if  present)  into  the  female 
connector on the PGHHD1 harness. Be sure to make a rm connection but do not 
force it. Plug the Black micro-t 24-pin connector on the PGHHD1 harness into the 
PXAMG Media Gateway box.
7. To complete the installation secure the Media Gateway (PXAMG) and HD Radio 
tuner (HDRT if equipped) 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.
8. 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 Media Gateway and 
HD Radio tuner before reinstalling the factory dash panels.
9. Note: The rst time you access the Gateway, 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 SAT mode again to begin normal gateway operation.
