Setup and Installation
Before beginning installation, ensure the vehicle's ignition is off and the battery is disconnected to prevent electrical shorts or damage.
- Locate Factory Antenna Connector: Identify the factory satellite antenna connector, typically found at the factory radio tuner or brain unit location. This connector is usually a proprietary type.
- Connect Adapter to Factory Antenna: Plug the appropriate end of the Metra 40-SIRXM-17 adapter into the factory satellite antenna connector. Ensure a firm and secure connection.
- Route Cable: Carefully route the 17-foot cable from the factory antenna connection point to the location of your aftermarket satellite radio tuner. Avoid routing the cable near hot engine components, sharp edges, or moving parts. Secure the cable using zip ties or clips to prevent rattling or damage.
- Connect Adapter to Aftermarket Tuner: Connect the other end of the Metra 40-SIRXM-17 adapter to the satellite antenna input on your aftermarket satellite radio tuner. This end is designed to fit standard aftermarket satellite antenna inputs.

- Test System: Turn on the vehicle and the aftermarket satellite radio system to verify proper signal reception and functionality.
Note: Professional installation is recommended if you are unfamiliar with automotive electrical systems or vehicle disassembly.
Operating Instructions
The Metra 40-SIRXM-17 is a passive adapter cable and does not require specific operating instructions beyond its proper installation. Once installed, its function is to transmit the satellite radio signal from the factory antenna to your aftermarket satellite radio tuner. The operation of your satellite radio system will depend on the aftermarket tuner itself.
- Ensure your aftermarket satellite radio tuner is powered on and properly configured according to its own user manual.
- Verify that the satellite antenna signal strength is adequate as displayed on your aftermarket tuner.
- If experiencing signal issues, refer to the troubleshooting section.
Maintenance
The Metra 40-SIRXM-17 antenna adapter requires minimal maintenance. It is designed for durability within the vehicle's environment.
- Periodic Inspection: Periodically inspect the cable and its connections for any signs of wear, damage, or loose connections, especially if the vehicle undergoes significant vibrations or temperature changes.
- Cleaning: Keep the connectors clean and free of dust or debris. If necessary, gently wipe with a dry, lint-free cloth. Do not use liquid cleaners directly on the connectors.
- Cable Protection: Ensure the cable remains securely routed and is not pinched, cut, or exposed to excessive heat or moisture.
