🔧 Before you start — head unit settings

1️⃣ Bluetooth IN — set to ADAPTER (factory default is OFF)
2️⃣ INT Mute — set to OFF
3️⃣ AUX+ Setup — set to OFF, it shares the same connector
4️⃣ Turn the ignition off and on again — the settings are not applied until you do
💡 INT Mute may disappear from the menu — that is normal once Bluetooth IN is set to ADAPTER
💡 A new BT Audio source appears — select it to play music
