Getting Started
1.1 Introduction
Thank you for purchasing the PAC’s iPAC-GM3 interface for OEM radios.
Designed for Video, Generation 3, 4, Mini, and Nano iPods. The IPAC-
GM3 has three Modes of operation; Advanced, Manual, and Auxiliary In-
put. Advanced Mode allows you to use your factory stereo buttons and
steering wheel audio controls (if equipped) to directly control your iPod.
In Advanced Mode the iPod text is displayed on the factory radio. Manual
Mode allows you to control your iPod directly using the click wheel con-
trols. Auxiliary input mode allows an external audio device to play through
your factory system.
The iPAC-GM3 works with vehicles that have navigation-equipped radios,
non-navigation radios, and vehicles equipped with XM satellite radio (refer
to section 2.1b for details). At the press of a button, you can switch be-
tween iPod, auxiliary input, and XM satellite radio (if equipped).
