A master reset (disconnect battery for 5 mins) often helps. | | Android Auto Won't Connect | Poor quality USB cable | Many users report this is the most common cause. Use a high-quality, short USB cable (<1m) directly connected to the phone. | | Bluetooth Pairing Fails | Device compatibility / Cache | Clear the Bluetooth cache on your phone. Try pairing manually from the phone’s Bluetooth settings instead of the receiver’s menu. | | No Sound During Calls (via Bluetooth) | Wiring or settings error | Check that the parking brake bypass is correctly wired. Re-pair the phone and ensure the call audio profile is enabled in Bluetooth settings. | | Spotify App Control Issues | App version mismatch | Ensure both the Spotify app and your phone’s OS are updated to the latest versions. |
