4.2. Kroky instalace
- Připravte vozidlo: Disconnect the negative battery terminal. Remove the factory radio from the dashboard.
- Kabelová připojení: Connect the wires from the GMOS-05 harness to the aftermarket radio harness according to the wiring color code (Section 4.1). Solder and heat-shrink all connections for reliability.
- Connect GMOS-05 Module: Plug the prepared GMOS-05 harness into the GMOS-05 interface module.
- Připojení vozidla: Connect the vehicle-specific connectors from the GMOS-05 harness into the factory wiring harnesses in the vehicle's radio opening.
- Navigační výstupy: If installing a navigation radio, connect the Light Green (Parking Brake), Blue (VSS), and Brown (Reverse) wires from the GMOS-05 harness to the corresponding inputs on your navigation radio.
- Testovací systém: Before reassembling the dashboard, reconnect the vehicle's negative battery terminal. Turn on the ignition and test the aftermarket radio, OnStar, and safety chimes.
- Upravit nastavení: Adjust OnStar volume and chime levels as described in Section 5.1.
- Konečná montáž: Once all functions are verified, securely mount the aftermarket radio and reassemble the dashboard.
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.
- Hlasitost zvonkohry: 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.
6. Údržba
The Axxess GMOS-05 interface module is designed for maintenance-free operation once properly installed.
- Ujistěte se, že všechna kabelová spojení jsou bezpečná a bez koroze.
