Installation Instructions for Metra 107-GM5B Car Audio Dash Kit

Quick guide from the manual

The Metra 107-GM5B is an installation kit designed for the 2010-2012 Cadillac SRX. It allows for the installation of aftermarket radios while retaining factory features such as climate controls, steering wheel controls, backup camera, and OnStar. Before beginning, disconnect the negative battery terminal. Ensure you have the necessary tools: panel removal tool, Phillips screwdriver, 9/32 inch socket wrench, and T-15 Torx screwdriver.

Dash disassembly

To access the radio, you must first disassemble the center console and dash:

• Use a panel removal tool to unclip and remove trim panels from both sides of the center console.
• Remove the 9/32 inch screws securing the padded trim and remove it.
• Unsnap the u-shaped trim around the lower dash pocket.
• Remove the screws securing the lower portion of the control panel and pull the pocket out.
• For navigation models, motorize the screen up, remove the trim over the top, unplug the control panel, and remove the screws/nut to extract the panel.
• Unclip and remove the control panel, then remove the screws securing the radio chassis to slide it out.

Kit preparation

Prepare the factory components for the new kit:

• For non-navigation models, remove the top trim panel, factory screen, and screen bezel.
• For navigation models, remove the factory screen bezel.
• Remove the clock panel, control button panel, and inner housing from the outer silver trim.
• Secure the 107-GM5B dash panel using factory screws.
• Cut off the top mounting legs from the main factory climate buttons and secure them to the new panel.
• Connect the lower climate controls, ensuring keyways are aligned.

Kit assembly

Depending on your radio type, follow the specific assembly instructions:

• ISO DDIN radio: Secure the radio brackets to the radio using the screws supplied with the radio.
• Pioneer Modular DDIN radio: Secure the display screen to the Pioneer display brackets, connect the RGB extension cable, and secure the assembly to the dash. Attach the Pioneer chassis brackets to the radio chassis.

Axxess interface installation and wiring

The Axxess interface retains factory features. Connect the 16-pin harness and car side harness to the interface. Follow the wiring diagrams provided in the manual for your specific vehicle configuration (amplified vs. non-amplified). Ensure the pink wire with the red bullet connector is connected to the climate control harness, or climate controls will not function. Connect the yellow RCA jack to the backup camera input to retain the factory camera.

Programming and steering wheel controls

To program the interface:

• Start the vehicle and connect the car side harness. The LED will flash to indicate radio detection.
• Wait for the LED to turn solid green, indicating successful programming.
• Chime volume can be adjusted using the potentiometer on the interface.
• Steering wheel controls can be remapped or assigned dual functions by following the specific button-press sequences outlined in the manual.

Final assembly

Once all connections are verified and the interface is programmed, secure the radio/bracket assembly to the dash using factory screws. Reassemble the dash in the reverse order of disassembly.
