In the actual use of TS car radio, users may encounter abnormal situations such as getting stuck in the startup logo or black screen, or clicking system upgrade without response. How should we solve them?

Step 1: After decompressing the system compressed file, copy all the files inside to a USB drive or SD card

Under the root directory, insert the USB drive or SD card into the machine;

Step 2: Completely power off the machine (B+and ACC must be disconnected simultaneously)

Step 3: Ground the square control wire on the power line again (either key1/key2 wire works)

Step 4: At this point, fully power on the machine (with both B+and ACC turned on simultaneously)

Step 5: After powering on, wait for the upgrade prompt to appear on the machine screen before releasing the control cable

Step 6: After the system upgrade is completed, the machine will automatically restart (update start upgrade)
