GMC Terrain 2017 no radio or backup camera issue, seeking radio code on GMC Terrain

Some 2017 GMC Terrain owners report experiencing issues with their radio and backup camera, often linked to power loss. These owners may encounter a security code requirement to unlock the radio, and sporadic shutdowns or a completely black screen have also been noted. Additionally, a black radio screen can result from various factors, including a frozen display, a non-functional radio unit, a dead battery, or a blown fuse. To resolve these issues, some owners find that resetting the radio can restore functionality, while others may need to reboot the system, install a new radio, replace the battery, or change a blown fuse. For those specifically seeking the radio code, it is recommended to consult the owner's manual or contact a local RepairPal Certified shop for assistance.
