I’ve been using Becker 4Digit Radio Code for a couple months now. It’s basically an app that helps you decode the 4-digit radio codes for Becker car radios. Pretty solid if you’re into that kind of thing.
Here’s what you do: you enter your car’s radio serial number and the app will generate a code for you. There’s also an option to save the codes, which is pretty convenient. And it’s got a built-in decoder that explains how to actually enter the code into your radio – took me a while to figure that out but it’s useful.
Look, if you’re a car audio enthusiast who needs to unlock Becker radios, you’ll probably like this. It’s not perfect – there’s a fee for each code generation which is kind of a bummer – but overall it does the job. Worth checking out if you need this specific functionality.
