Most wireless Android Auto connection problems come from pairing records, phone power controls, the wrong USB port or an interrupted Wi-Fi handoff. Work through the steps below in order.
Start with a clean pairing
Delete the adapter from the phone’s Bluetooth list and remove the phone from the vehicle’s paired-device list. Restart the phone and vehicle, then pair again according to the adapter instructions.
Confirm the wired baseline
Connect the phone directly to the vehicle using a reliable data cable. If wired Android Auto does not work consistently, the adapter cannot correct the underlying USB or head-unit issue.
Review phone settings
- Enable Bluetooth, Wi-Fi and location permissions where required
- Allow Android Auto to run in the background
- Disable battery optimization for Android Auto during testing
- Temporarily disable VPN or hotspot functions
Check power and USB
Use the port that originally launches Android Auto. Avoid unpowered splitters and replace damaged extension cables. If the adapter restarts repeatedly, power stability may be the cause.
Update carefully
Use only firmware supplied for the exact adapter model. Record the current version before updating and keep the vehicle powered throughout the process.
If the issue persists, provide the vehicle model, year, phone model, Android version, adapter firmware and a short video to technical support.

How do I fix Android Auto pairing failures?
Remove the old Bluetooth pairing on the phone, confirm the car supports factory wired Android Auto, and re-pair. Ensure the adapter is on current firmware.
