What goes out if the rdo fuse is blown?

If the RDO (Radio Data Output) fuse is blown, the radio or audio system in the vehicle will lose power and cease to function. This may also affect other components that rely on the RDO circuit, such as information displays or auxiliary audio inputs. Additionally, any settings or presets stored in the radio may be lost if the system has no backup power. To restore functionality, the blown fuse must be replaced.
