ໝາຍເຫດ: This wiring diagram is a general guide. Always refer to the specific wiring instructions provided with your aftermarket radio and vehicle for precise connections.

4.2. ຂັ້ນຕອນການຕິດຕັ້ງ

ກຽມລົດ: Disconnect the negative battery terminal. Remove the factory radio from the dashboard.
ການເຊື່ອມຕໍ່ສາຍ: 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.
ການເຊື່ອມຕໍ່ຍານພາຫະນະ: Connect the vehicle-specific connectors from the GMOS-05 harness into the factory wiring harnesses in the vehicle's radio opening.
ຜົນການນຳທາງ: 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.
ລະບົບການທົດສອບ: Before reassembling the dashboard, reconnect the vehicle's negative battery terminal. Turn on the ignition and test the aftermarket radio, OnStar, and safety chimes.
ປັບການຕັ້ງຄ່າ: Adjust OnStar volume and chime levels as described in Section 5.1.
ສະພາສຸດທ້າຍ: 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.
ລະດັບສຽງຂອງກະດິ່ງ: 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. ບໍາລຸງຮັກສາ

The Axxess GMOS-05 interface module is designed for maintenance-free operation once properly installed.

ບັນຫາທົ່ວໄປແລະການແກ້ໄຂ
ບັນຫາ	ສາເຫດທີ່ເປັນໄປໄດ້	ການແກ້ໄຂ
No audio from aftermarket radio.	Incorrect speaker wiring; no power to radio; interface not initialized.	Verify all speaker wires are correctly connected. Check 12V constant and accessory power. Ensure the interface is properly connected to the vehicle's data bus.
OnStar or safety chimes are not working or are too loud/quiet.	Incorrect connection to GMOS-05; volume potentiometers need adjustment.	Confirm the GMOS-05 module is properly connected. Adjust the "OnStar Vol" and "Chime Vol" potentiometers on the module (refer to Section 5.1).
Aftermarket radio does not power on.	No 12V constant or accessory power; blown fuse.	Check the vehicle's fuse box for blown fuses. Verify the Yellow (constant) and Red (accessory) wires are correctly connected and receiving power.
Navigation features (e.g., parking brake, VSS, reverse) are not functioning.	Outputs from GMOS-05 not connected to navigation radio.	Ensure the Light Green, Blue, and Brown wires from the GMOS-05 are correctly connected to the corresponding inputs on your navigation radio (refer to Section 4.1).

If troubleshooting steps do not resolve the issue, contact Axxess technical support or a certified installer.
