Connect iPod to GMPD3 iPod dock connector. Plug the connector in straight. Do not insert the 
cable at an angle or wiggle the cable during insertion.

Detailed Installation Guide

Turn your vehicle off and disconnect the negative terminal of your battery. Confi gure the DIP swtiches on the rear of the 

GMPD3 module (see page 3 for details). 

If your vehicle is not equipped with a factory XM tuner, connect the included “T” harness to the GMPD3 module and use 

the following steps suffi xed with a. If your vehicle is equipped with a factory XM tuner, connect the included “Y” harness 

to the GMPD3 module and use the following steps suffi xed with b.

If your vehicle 

is not

 equipped with a factory XM tuner, the GMPD3 will interface directly to the back of your factory 

radio. Consult factory literature or professional help for detailed radio access information. Generally, the trim panel 

around the outside of the radio will pull free on late model radios, exposing the bolts holding the radio in place. Remove 

the bolts (7mm) to view the desired connections (other radios may require extra panels to be removed before the back of the radio 

can be viewed). The radio may contain several connectors, but only two will match the connectors on one of the included GMPD3 

“T” harnesses. Locate the matching connectors and disconnect them from the factory radio. These connectors are typically 14-pin 

and 16-pin; however, depending upon the vehicle, the number of pins may differ.  Ensure that you only disconnect the connectors 

that match the GMPD3 “T” harness. 

If your vehicle 

is

 equipped with a factory XM tuner, the GMPD3 will interface directly with your factory XM module. Locate 

the XM module in your vehicle or consult with a professional for help. Typically, the XM module is located behind the glove 

compartment in SUVs or in the back deck in cars and “crossover” vehicles. The XM module has a single 16-pin connector 

and an antenna connected. Disconnect the 16-pin connector from the factory XM module. 

Connect the factory 14-pin and 16-pin connectors that you disconnected from the radio in step 

3a

 to the matching 

locations on the GMPD3 “T” harness.

Connect the factory 16-pin connector that you disconnected from the XM module in step 

3b

 to the matching location 

on the GMPD3 “Y” harness.

Connect the remaining 14-pin and 16-pin connectors on the GMPD3 “T” harness to the matching locations on the back 

of the factory radio.

Connect the remaining 16-pin connector on the GMPD3 “Y” harness to the matching location on the factory XM

Connect the iPod dock connector cable to the GMPD3 module. You may also connect an optional AUX input to the RCA 

connectors on the GMPD3 module (white = LEFT, red = RIGHT).

Mount the GMPD3 module either behind the dash or glove compartment (mounting hardware not included). Be careful 

not to drill into wiring or vehicle mechanisms. You are solely responsible for securely fastening the GMPD3 in your 

vehicle. Ensure that the iPod dock connector is left in a convenient place for connection to your iPod/iPhone.

Connect your iPod to the GMPD3 dock connector. Plug the connector in straight. Do not insert the cable at an angle or 

wiggle the cable during insertion.
