Question about Metra 99 9104 99 9104 Stereo Installation Kit for 06 Audi A3
It sounds as if you have dropped the constant live feed to the unit somehow. The constant feed keeps the power fed to your unit/system for memory backup. This also includes your code.
The code must be used and entered when the unit is removed from the vehicle, or the constant power source is disconnected from the unit. When constant power is restored to the unit, the security code must be entered before the unit becomes operational.
Hope it helps
