Mazda Speed Protege Head Unit Forgets Radio Settings



Issue: Headunit Forgets Audio Settings.
What: Headunit forgets audio setup settings or clears memory after resetting due to above problem.

Why: Unknown as to why it does it by itself. It is normal behavior, however, when you manually reset the unit.

How To Fix: If your deck resets without you manually resetting it, return to the dealership. They should replace it under warranty. The default settings are listed below so you can reset it while you're waiting for the new unit. Keep in mind that the below settings are "optimized defaults" and you are urged to change as you feel needed.
