Here's the video guide.

1. Solution

1-1. USB port connection

Ensure the cable is connected to a data-only USB port.

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.

1-4. Please update the firmware to the latest version

You can download the latest AutoPro X app through this link >

Be sure to update the firmware to the latest version. Please refer to the guide video >

1-5. Please try GM mode if you have GM or Honda cars.

For GM and Honda cars, you need to switch to GM mode inside the AutoPro X app. Here’s the app link. You can turn on GM mode in the app by first tapping the gear icon in the top right corner, then selecting “Specific Device Configuration,” and enabling GM mode.

STEP01 Connect AutoPro X to the app. (Grant all permissions)

STEP02 Tap the gear icon in the top-right corner.

STEP03 Choose Specific Device Config and turn GM mode on.

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.
