My avn520 car stereo is locked - Cars & Trucks

If its locked then to unlock it the radio system needs to be reprogrammed.

To reprogram the radio there is 4 digit code. That code has to be inserted, once these code is inserted, your car radio will get into its actual setting where you can set/select your radio setting.

Many a time's radio asks for the code after car battery is disconnected.

On some cases to retrieve the code its mentioned in manual or else car dealer is other option to get car radio code.
