Introduction
The Connects2 CTSGM-49 Radio Replacement Module is designed to facilitate the installation of an aftermarket car stereo in select GM vehicles manufactured between 2004 and 2016. This module ensures the retention of critical factory functions, including steering wheel controls and various vehicle chimes, while preventing fault codes in the vehicle's Electronic Control Module (ECM).
Product Features
- Radio Replacement Simplification: Streamlines the integration of an aftermarket head unit into your vehicle's existing electrical system.
- Steering Wheel Control (SWC) Retention: Maintains the functionality of your factory steering wheel buttons for audio control (volume, track, etc.).

- ECM Fault Code Prevention: Sends correct data to the vehicle's ECM to prevent fault codes that can occur when the factory radio is removed, ensuring proper vehicle diagnostics.
- Accessory Power Output: Provides a +12V switched accessory power source (rated at 0.3A) for the aftermarket radio. Note: This output is not intended to power the head unit directly.

Installation Guide
Installation of the CTSGM-49 module requires basic automotive electrical knowledge. It is recommended to consult a professional installer if you are unsure about any steps. Always disconnect the vehicle's battery before beginning installation.
General Installation Steps:
- Prepare Vehicle: Ensure the vehicle's ignition is off and disconnect the negative terminal of the battery.
- Remove Factory Radio: Carefully remove the existing factory radio from the dashboard.
- Connect Wiring Harnesses: Connect the vehicle-specific wiring harnesses from the CTSGM-49 module to the vehicle's factory wiring. Ensure all connections are secure.
- Connect Aftermarket Radio: Connect the other end of the CTSGM-49 harnesses to your aftermarket car stereo's wiring. Pay close attention to power, ground, speaker, and accessory wire connections.
- Integrate Chime Speaker: Connect the provided chime speaker to the designated output on the CTSGM-49 module. Position the speaker in a location where chimes can be clearly heard but are not obstructed.
- Module Placement: Securely mount the CTSGM-49 module in a safe, dry location behind the dashboard, away from moving parts or heat sources.
- Test System: Reconnect the vehicle's battery. Turn on the ignition and test the aftermarket radio's functionality, including audio, steering wheel controls, and factory chimes. Verify that no new warning lights appear on the dashboard.
- Reassemble Dashboard: Once all functions are confirmed, carefully reassemble the dashboard components.
For detailed wiring diagrams and specific vehicle instructions, please refer to the comprehensive installation manual provided with your product or consult the manufacturer's website.
Operation
Once installed, the Connects2 CTSGM-49 module operates automatically to maintain factory functions. There are no user-adjustable settings on the module itself.
Steering Wheel Controls:
Your factory steering wheel controls will function as they did with the original radio, allowing you to control basic functions of your aftermarket head unit such as:
- Volume Up/Down
- Track Up/Down (Next/Previous)
- Mode/Source Selection
- Call Answer/End (if supported by your aftermarket radio and vehicle)
The specific functions retained may vary slightly depending on your vehicle's original configuration and the capabilities of your aftermarket radio.
Factory Chimes:
All factory chimes (e.g., seatbelt warning, door ajar, low fuel, park assist) will continue to sound through the dedicated chime speaker provided with the module. The volume of these chimes is typically controlled by the vehicle's factory settings or is fixed.
Troubleshooting
If you encounter issues after installing the CTSGM-49 module, consider the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to aftermarket radio. | Incorrect wiring, blown fuse, or module not receiving power. | Check all wiring connections, especially power and ground. Verify vehicle fuses. Ensure the module is properly connected to the vehicle's power source. Remember the module's accessory power output is 0.3A and not for powering the head unit directly. |
| Steering wheel controls not working. | Incorrect SWC wiring, incompatible aftermarket radio, or vehicle not supported for SWC retention. | Verify the SWC wires are correctly connected between the module and the aftermarket radio. Check your aftermarket radio's manual for SWC input configuration. Confirm your vehicle model and year are listed as supporting SWC in the compatibility table. |
| No factory chimes or chimes are too quiet/loud. | Chime speaker not connected, faulty speaker, or incorrect module connection. | Ensure the chime speaker is securely connected to the module. Check the speaker for damage. Verify all module connections are firm. Chime volume is typically fixed by the vehicle's system. |
| Check Engine Light or other warning lights appear. | Module not communicating correctly with vehicle's ECM. | Double-check all module connections. Ensure the module is receiving proper power and data signals. If issues persist, consult a professional installer or vehicle technician. |
