Connecting and Troubleshooting 2din 7080b Radio from Aliexpress in Volkswagen Golf 4

Hello yesterday I received a radio 2din 7080b from aliexpress after connecting everything worked until the launch and launch. Then the screen turned blue and in the upper left corner it wrote "undoing" as if the rearview camera was attached but it is not attached. I noticed that when the ignition key switches on, it switches back on and when I turn off everything goes back to normal. The score was trying to play with it but it did not work and eventually it looks like this.
Any ideas how to fold it ?? Car Volkswagen Golf 4

Have you read any documentation from this radio?

Poorly connected. The diagram is on the radio. You only need to connect 11 wires. 8 to speakers. 2 power and mass.
