If the device cannot be connected or recognized, you can use the USB Flash drive to upgrade the firmware. Of course, to avoid malfunctions, if you can upgrade online，and you'd better do that. Otherwise, the equipment is likely to become useless. This upgrade method is different from the past, you need to pay 100 % attention to following our upgrade steps, otherwise the dongle will be dead.
(Very Important note: Do not attempt to connect the adapter to your computer's or laptop's USB port. These ports are made to transfer data and will just interrupt the update process and break the device.)

1. Prepare a USB flash drive, format it to FAT32/Allocation unit size 1024bit or default.

4. Insert the USB flash drive into the SMART-BOX Standard and wait at lest 4 minutes while the device being updated (You will see alternative red light and green light on the device and finally it stays red.)
5. Delete all Wi-Fi and Bluetooth from Phone and Car (then make sure both Bluetooth and Wi-Fi are turned on in the phone, but keep "not conneted".)
6. Please unplug SMART-BOX Standard from the USB wall power outlet/charger and remove the USB flash drive from the SMART-BOX Standard.

After a successful upgrade, you can return to the car for testing. Good luck!
Synchronization Mode (normal, compatible):
The default is normal, which is used to solve the problem of out-of-sync information displayed on the dashboard.
Compatibility: Solve the problem that some cars cannot connect to the SMART-BOX Standard.
Media sound quality (CD, DVD):
Default DVD, which has better sound quality.
CD, to solve the problem of noise in certain cars.
Media delay (300~2000 milliseconds):
The default is 1,000. The greater the delay, the less likely to be stuck, and the shorter the delay, the more synchronized music and images will be. This delay setting is related to the network environment in the car and can be adjusted according to the actual situation.
