Reason 2: Radio Completely Dead

If your radio screen remains black even after attempting a system reboot. It is possible that the radio unit itself is entirely non-functional and it may start from unavailable FM radios. In such cases, the best solution is to install a new radio.

Solution: Install New Radio

  • Gather the necessary tools for the installation, including a trim removal tool, wire connectors, electrical tape, and a socket wrench set.
  • Disconnect the negative terminal of the vehicle’s battery to ensure safety during the installation process.
  • Use the trim removal tool to carefully remove the trim panel surrounding the existing radio unit.
  • Unplug the electrical connectors and remove the mounting screws or bolts that secure the old radio in place.
  • Take out the old radio unit and disconnect any remaining wiring connections.
  • Connect the wiring harnesses and antenna adapter to the new radio unit, ensuring a secure and proper connection.
  • Slide the new radio unit into the dashboard, align it with the mounting brackets, and secure it in place with the appropriate screws or bolts.
  • Reconnect the electrical connectors and antenna.
  • Carefully reinstall the trim panel around the new radio unit.
  • Reconnect the negative terminal of the battery.
  • Test the new radio unit to ensure it is functioning properly and displaying correctly on the screen.

Reason 3: Dead Battery

Another reason for a black radio screen could be a dead battery. If the battery is low or completely drained, it may not provide sufficient power to the infotainment system, resulting in a black display. To fix this issue, you will need to replace the dead battery.

Solution: Replace the Dead Battery

  • Ensure that the vehicle is turned off and in the park, and engage the parking brake for safety.
  • Open the hood of your GMC Terrain and locate the battery, usually located in the engine bay.
  • Use a wrench or socket wrench to loosen and remove the negative (black) terminal connector from the battery.
  • Repeat the same process for the positive (red) terminal connector.
  • Carefully lift the old battery out of its tray and set it aside.
  • Clean the battery tray and terminals with a battery terminal cleaner or a mixture of baking soda and water to remove any corrosion.
  • Place the new battery into the tray, ensuring it is secure and properly aligned.
  • Connect the positive (red) terminal connector to the positive terminal of the new battery, and tighten it with a wrench.
  • Repeat the same process for the negative (black) terminal connector, ensuring a secure connection.
  • Close the hood of the vehicle and start the engine to test the new battery and verify that the radio screen is now functioning properly.

Reason 4: Blown Fuse

A blown fuse can also cause the radio screen to go black. Fuses are protective devices that prevent damage to electrical components by interrupting the flow of electricity in case of a power surge or short circuit. If a fuse related to the radio system blows, it can result in a black screen.

Solution: Replace the Blown Fuse

  • Locate the fuse box in your GMC Terrain. The fuse box is typically located in the engine compartment or on the driver’s side dashboard.
  • Consult the owner’s manual or fuse box cover to identify the specific fuse related to the radio system. The diagram or labeling will indicate which fuse corresponds to the radio.
  • Use a fuse puller tool or a pair of needle-nose pliers to carefully remove the blown fuse from its socket. Grip the fuse firmly and pull it straight out.
  • Inspect the blown fuse to confirm that the metal strip inside is broken or damaged. If so, it needs to be replaced.
  • Take a new fuse with the same amperage rating as the blown fuse. It is important to use the correct amperage to prevent electrical issues or damage.
  • Insert the new fuse into the appropriate slot in the fuse box, aligning it with the socket. Make sure it fits securely and is seated properly.
  • Firmly push the fuse into place until it is fully inserted and flush with the fuse box.
  • Close the fuse box cover if applicable.
  • Turn on the ignition and check if the radio screen is now displaying properly.
