- OnStar Interface for Class 2 vehicles with Bose sound systems. Same as OS-2 above but without an onboard amplifier for OnStar audio. The OnStar audio is amplified using the factory amplifier.
- OnStar Volume control via factory steering wheel audio controls on selected vehicles*. Radio controls can be retained to control new radio by using PAC's SWI-X.
- Unlike some other interfaces on the market, 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.
- Retains door chimes when used with optional CM1 chime module. Also retains Vehicle Parking Assist chimes.
- So universal it works with Premium Bose or Standard Bose sound systems.
- 1. These headunits have 5 or more EQ settings. If the unit has only 3, then the OS-2 and CM1 are required. First half of 2004 have 5or more EQ settings and second half of 2004 use only 3 EQ settings. 2 . The OS-2Bose 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 the factory Bose amplifier is not being used, use the OS-2 interface. 4. *These vehicles have a premium Bose amp that only accepts 2 channel audio inputs. The aftermarket radio will not fade, however it will still continue to balance. 5. You may use this interface even if the vehicle does not have OnStar but need to interface the Bose amplifier. Note 2: If you take your vehicle to the GM dealer to have it upgraded with a new software update, please remove this product prior to going to the GM Dealer. The reason is that the product does not go into offline mode which will show as an error to the scan tool the dealer uses.
