If a radio resets everytime you turn on your car you would need to double check the wiring. If your vehicle sat for 9 days and all your settings and presets were still there, that indicates the wiring is correct
However, if the unit is intermittently turning on and off, with the vehicle off. we would have you check your wiring. Please be 100% sure that you are running your power wires separately.
RED wire needs to see a switched 12VDC .
YELLOW wire needs to see a constant 12VDC.
Please create a support ticket once you have checked your wiring.
Create a Ticket for warranty service/exchange for the head unit and or any other unit you are experiencing problems with so we can service or exchange them.
