head unit not power on

[yanivos89]

Hello friends,
Today I received the multimedia system that I ordered from AliExpress and of course the frame did not arrive compatible with the car (as I was promised),
But I improvised and managed to overcome it,
The problem is that I connect all the cables properly and the system just does not turn on,
Maybe I'm missing something and I don't know? I even tried replacing the fuse, but nothing.
In the video you can see everything, although in the video I only connect the power cable, but before that I tried with everything... the system should turn on even when nothing is connected except the power cable, right?
I would appreciate your help because I am at a loss and the seller is not really helpful..

either take it in and let a professional look at it, return it, or get a new one. there really is not much a forum hear can do for you.

Check you've got the GROUND(might be black), CONSTANT/BACKUP(might be yellow or blue), and POWER(might be red) wires all connected correctly. FYI CONSTANT/BACKUP goes straight to the 12V and is always on, and POWER goes to the accessory position on the ignition, and is only on when the key is turned.

However if you don't have the correct wiring harness for the head-unit, I strongly suggest NOT bodging it in case it blows up, starts a fire, etc. As @ocnbrze posted have a professional auto electrician install it, or return it.

I have uploaded the pictures of the cables, I would appreciate a more specific direction regarding which other cable is responsible for giving power to the system

Looking at your pics, to me it looks like it almost certainly needs the correct wiring harness adapter for the head unit to successfully fit it to your car, mainly because of the connectors it uses.

There's information here about Android head unit wiring.

Why don't you give us pertinent information, such as the make, year and model of the car, along with the exact model of the head unit...
Maybe then we can make some headway

Is it a VW you've got? But I do think you'd definitely need the correct wiring adapter for your make and model of car to connect this Android head unit to it.
