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 in the passenger side of the trunk to access the 
XM Satellite Radio tuner.  This will provide access  to the  factory radio  connectors 
where you will connect the Media Gateway harness.
3. Disconnect the factory 20-Pin harness from the Satellite Radio tuner.
4. Connect  the 8-Pin iPod docking cable into the  rst  port on  the  Media Gateway 
(farthest away from dipswitches). Carefully run the 20 foot iPod cable 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 vehicle 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)  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 PGHHD2C harness into the 20-pin port on the 
XM Satellite Radio tuner. Next, connect the factory 20-pin harness into the female 
connector on the PGHHD2C harness. Be sure to make a rm connection but do not 
force it. Plug the Black micro-t 24-pin connector on the PGHHD2C 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 with the XM Satellite Radio tuner. 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 trunk, 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.
