The Metra OnStar Class II interface makes it easy to use the OnStar service on vehicles from most major manufacturers. The device enables you to easily adjust the volumes of your OnStar feedback systems and automobile chimes with a few quick clicks.
Add Navigation Support
Each Metra OnStar Class II interface allows you to connect your vehicle to many modern navigation systems. This enables the use of GPS positioning through the OnStar system and lets you use GPS navigation tools and apps.
Balance and Fade
The interface kit also gives you control over the balance and fade of your OnStar and auto chime systems. Balance allows you to divide sounds between the driver and passenger sides of the vehicle. Fade gives you the ability to direct the sound to the rear of the vehicle or the cabin. Both balance and fade provide intermediate settings as well as complete sound shifts.
Each Metra OnStar Class II interface can receive updates to its firmware or onboard applications through a USB connection. This allows you to keep up with the latest OnStar updates and ensure your system remains compatible with the apps you choose to employ.
