My car audio system fails to initialize upon starting the car sometimes. It does not play any radio, Bluetooth, gps, or menu navigating noises. It still does play alarms.
If I turn the car off and on it occasionally works and once I get it to work it usually works for the rest of the day. I checked both amp fuses. I am not even sure where to start for this issue.
Request advice.

If it works at all it's not the fuses. Sounds like a possible grounding issue or a defective head unit.
