TBox is not recognized/does not work，What should I do？
1, Restore the factory settings of the Automotive Head Unit
2, Try to upgrade the latest version of firmware
3, Observe the status of the TBox signal light: after connecting the USB port, within 30 seconds, if the signal light is no longer on, then you need to use a two-part cable to increase the power supply.
① USB Female to CarlinKit product
② USB Male to car cigarette lighter/charging
③ USB Male to car data port（USB/Type-C are both possible, Depending on the data cable you purchase）
