6. Secure Wiring and Reinstall RNS-E: Route all cables neatly and securely to prevent pinching or interference. Reinstall the RNS-E navigation unit back into the dashboard.
7. Reconnect Battery: Reconnect the vehicle's battery negative terminal.

Operating Instructions

1. Power On: Turn on your vehicle's ignition and the RNS-E navigation system.
2. Select AUX Audio Source: On your RNS-E unit, navigate through the audio source options until you select "AUX" or "CD Changer" (depending on your system's configuration). This will activate the input from the Bluetooth adapter.
3. Pairing with Bluetooth Device:
   • On your mobile phone or other Bluetooth-enabled device, go to the Bluetooth settings.
   • Search for available devices. The adapter should appear as a discoverable device (e.g., "Bluetooth Music" or similar).
   • Select the adapter to pair. No password is typically required.
   • Once paired, your device will confirm the connection.
4. Playing Music: Once paired, you can play music from your mobile phone or other device. The audio will be transmitted wirelessly to your RNS-E system and played through your car's speakers. Control playback (play/pause, skip tracks) directly from your paired device.
5. Hands-Free Calling: When a call comes in, the audio will automatically switch to the hands-free mode. Speak into the external microphone for clear communication. End calls from your phone.

• Confirm that the RNS-E software index is at least 650.
