5. Operating Features and Adjustments
The GMOS-05 interface retains several factory features and allows for adjustments to optimize your audio experience.
5.1. OnStar and Chime Volume Adjustment
The GMOS-05 allows for independent adjustment of OnStar volume and safety/warning chime levels. This is typically done via potentiometers (small adjustment screws) located on the GMOS-05 module itself.
- OnStar Volume: Locate the potentiometer labeled "OnStar Vol" or similar on the module. Use a small screwdriver to turn clockwise to increase volume, counter-clockwise to decrease.
- Ҳаҷми занг: Locate the potentiometer labeled "Chime Vol" or similar. Adjust as needed to ensure safety chimes are audible but not overly loud.
Perform these adjustments with the vehicle running and the aftermarket radio powered on to accurately gauge the sound levels.
5.2. Navigation Radio Outputs
The GMOS-05 provides dedicated outputs for aftermarket navigation radios, which require specific vehicle data for proper operation.
- Parking Brake Output: Signals when the parking brake is engaged, often required by navigation units for certain functions.
- Vehicle Speed Sense (VSS) Output: Provides vehicle speed data for accurate navigation tracking.
- Reverse Output: Activates when the vehicle is in reverse, useful for aftermarket backup cameras or navigation features.
