Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and a fuse puller.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the vehicle battery to prevent electrical shock.

2. Inspect and Replace Fuses

Locate the fuse box (typically in the glove compartment or under the dashboard).
Use a fuse puller to remove the fuse related to the radio (check the owner's manual for the exact fuse number).
Inspect the fuse for continuity; replace it if blown with a fuse of the same amperage.
Reinstall the fuse and reconnect the battery.

3. Check Wiring and Connections

Remove the radio unit from the dashboard using a socket set.
Inspect the wiring harness and connectors for signs of damage, corrosion, or loose connections.
Clean any corroded connections with electrical contact cleaner.
Ensure all connectors are securely reattached before reinstalling the radio.

4. Perform a Soft Reset

Disconnect the negative terminal of the battery.
Leave it disconnected for 5-10 minutes to allow the system to reset.
Reconnect the negative terminal and ensure it's tight.

5. Reprogram or Update Software

Use the OBD-II scanner to check for any software-related error codes.
If necessary, visit a BMW dealership or use the BMW ConnectedDrive app to check for available updates for the radio system.
Follow the dealership's or app's instructions to apply any necessary software updates.
