- 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.

Note 1: 1. These headunits have only 3 EQ settings. If the unit has only 5 or more EQ settings, then the OS-2BOSE is required. First half of 2004 have 5or more EQ settings and second half of 2004 use only 3 EQ settings. 2. 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. 3. 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. 4. FAQ's about GM's Class 2 here.
