If your car radio does not have an AUX connection, there are other ways to connect your devices such as mobiles or tablets and play music or other audio signals.

### Alternatives to AUX:
- Bluetooth: Many modern car radios have Bluetooth functions that allow you to connect devices wirelessly and transmit audio signals. Check whether your car radio supports Bluetooth.
- USB port: Some car radios have USB ports that you can use to connect devices such as smartphones or MP3 players. Make sure that the device is compatible and has the necessary drivers or software.
- Adapters and converters: If your smartphone or tablet no longer has an AUX output, you can use an adapter that converts the smartphone's charging socket into an AUX output. There are also adapters that enable Bluetooth connections if your car radio supports Bluetooth.

### Connection via other connections:
- Micro USB or other connections: Check the available connections on your car radio and your device to see if there are other connection options, such as micro USB or special adapters for the connection.

These alternatives allow you to connect your devices to the car radio and play audio signals even without an AUX connection.
