This is typically a device driver issue that occurs when a device is plugged into your computer for the first time without downloading the Device Updater first.
First and foremost; MAKE SURE YOU ARE USING A USB CABLE WITH DATA TRANSFERABILITY. NOT A CHARGING-ONLY CABLE. (The included cable is a data cable.)
Step 1. Disconnect your device from the computer (Do not reconnect the device until step 4)
Step 2. Completely Uninstall the Device Update software from your computer
Step 3. Reinstall the Device Updater software, the device drivers are installed in the same instance as the Device Updater.
Step 4. Reconnect your device to see if the problem has been resolved. (For GTX- plug in the VIM, NOT the head unit)
