PAC OS-2 OnStar Interface
The PAC OS-2 OnStar® Interface for Class 2 non-Bose® vehicles. The OS-2 uses a Data Link Controller chip (DLC) that is specifically designed for connecting to GM's Class 2 data bus. Allows you to add an aftermarket head unit to your 2004 Grand Prix and not have to relocate your stock headunit, or lose chimes or OnStar!
Safe & Sound Class 2 circuitry will not disable vehicle data bus even if interface loses power.
When OnStar® is active, the OS-2 will keep OnStar® on even when the key is removed and the door is opened. OnStar® will turn off when the call is complete.
OnStar® active LED and Ignition on LED for visual indication.
Provides +12v switched accessory output. No more searching for switched +12v in fuse box or kickpanel.
Smart Sense Mute output to either mute the aftermarket radio or to turn it off when OnStar® is active.
Retains door chimes when used with optional CM1 chime module.
New radio will operate with the vehicle RAP (Retained Accessory Power) system. The radio stays on after the key is turned off and stays on for aproximately 10 minutes or until a door is opened.
We also have the PAC CM1 chime module for use with the OS-2 or OS-2Bose® interfaces only. The CM1 retains the warning chimes when you replace the factory radio that have the warning chimes built into it. Keeps seat belt, low fuel, parking brake, memory seats, security, low brake fluid and other chimes. The OS-2 is required to use the CM1.
Applications:
2004 Pontiac-Grand Prix
2000-2004 Chevrolet- Monte Carlo
2004 Chevrolet - Silverado, Venture
2002-2004 Chevrolet- Trail Blazer non-Bose®, Envoy SLE

2001-2004 Pontiac - Montana

Notes:
The OS-2 does not retain the factory XM receiver, rear seat DVD or the rear center console controls. You will lose the XM/DVD and rear console option when the factory radio is replaced with an aftermarket radio.
If you are not retaining the Bose® amplifier, use this OS-2 interface instead of OS-2Bose® interface. CM1 is also required if Bose® amp is bypassed
