I’m unable to send photos; could you contact me on WhatsApp instead? My number is +86 183 2087 0296.

I apologize, but we are unable to control the air conditioning via the screen; I have already discussed this with our engineers.

Do not use an adapter cable for the black wire connected to the original vehicle display; keep it as is and leave it installed with the original display.

Yes, air conditioning controls cannot be operated via an aftermarket head unit.

Please take a photo of the KEY wire connections for verification; there is an issue with how your wires are connected.

Take photos of the original head unit's connector pinout and the screen's connector pinout, as well as photos of the labels on the aftermarket wiring harness.

Does the main unit display a pop-up when you adjust the buttons on the air conditioning panel?

Take a photo of the CANBOX.

Installation is also possible using FTF1.

Take a photo of the CANBOX version; this information can be found within the head unit.
