### 1-2. **Check if your car has android auto.**

If you don’t have Android Auto built into your car, AutoPro X isn’t compatible. Please confirm whether your car has Android Auto first.

### 1-3. **Please turn on Android Auto in your car's settings**

In some cases, users may have turned off the Android Auto settings inside the car. Please check if Android Auto is turned on in your car.

### 1-6. **Please use our cable which was included with our dongle.**

Our cable is specifically designed for AutoPro X. If you used another brand’s cable, it might be causing the issue.

**Please try USB cable.**

We’ve encountered some issues with C-to-C cables. If your car has a C port, the cable might be causing errors. Please try an A-to-C cable or a Samsung-provided cable instead.

### 1-7. **If you have a Toyota or Lexus released before 2023, Please use black cable**

you’ll need to use the black cable that comes with the dongle. Please connect it and plug into both the charging and USB ports.

If none of the above options are helpful, please revert to the previous version.
