How do you fix a car lighter when the actual car lighter adapter works but when plugging in a GPS or Satellite radio plug it doesnt work?

If the car lighter adapter works but devices like a GPS or satellite radio do not, first check the device's plug for any debris or damage. Ensure the device is compatible with your car's power outlet specifications. If the device still doesn't work, try using a different car lighter outlet or test the device in another vehicle to rule out issues with the device itself. If necessary, inspect the vehicle's fuse related to the power outlet and replace it if it's blown.
