1. Blown Fuse: Check the fuse responsible for the car stereo and radio charger. If the fuse is blown, replace it with a new fuse of the same amperage.
2. Loose Connection: Ensure all connections (power, ground, and speaker wires) are secure and not loose.
3. Faulty Wiring: Inspect the wiring for any damage or corrosion. Replace or repair any faulty wiring.
4. Faulty Head Unit/Charger: If the stereo and charger were both working when you left, it's possible that one or both components have developed a fault. Try disconnecting and reconnecting the head unit and charger to see if that resolves the issue. If not, they may need to be repaired or replaced.
5. Battery Issues: Check the car's battery to ensure it has sufficient charge. If the battery is weak or dead, it may not provide enough power to the stereo and charger.
6. Radio Frequency Interference: If the car stereo and charger were working when you left, but there's a new source of radio frequency interference in the area (e.g., a new transmission tower or nearby construction), it could disrupt their operation.
