Hello, hello. In this video, I'm going to show you how to connect an Android radio from scratch
0:09
step by step. Here's the radio panel. We can see that there are a lot of connections
0:19
let's go through them one by one. This one here is the antenna, it's the connector
0:23
Here, for example, I have an internal indoor antenna and this goes connected here
0:34
This side is the GPS antenna, it's the one used for the navigator or for the radio to
0:39
tell you the speed at which the vehicle is traveling. This is rolled up like this
0:48
An SMA connector is placed and rolled up until it doesn't turn anymore
0:53
And this is glued to a well-exposed part of the car, away from metal parts
0:59
It's usually left at the end of the dashboard or on the column in front of the doors as
1:03
high as possible so that it gets the best possible signal. That's it
1:10
Let's move on to the other connectors. This connector is the main branch where all the connections go, from the radio's power
1:22
connection to the battery as well as the speakers. Here we are going to show another branch where everything is ready
1:41
This goes here and here goes the original connection to the one your previous radio went to
1:47
There are other cables here that are essential. This one, for example, that says, back, or that in some cases says, camera, is the one that goes to the reverse camera, the one that sends the signal to the reverse camera
2:03
So that, once you put the car in reverse, the radio changes and shows you what the reverse camera shows
2:09
These that say key, K1 and 2, are to connect the steering wheel control
2:19
In radios that have steering wheel control, you can connect them so that the buttons remain
2:24
working and you can control the radio from the steering wheel Well and in this main wiring here go the speakers There are 4 speaker cables there are 4 channels and there are 8 cables in total 4 positive and 4 negative
2:44
And here also go the negative cables, the standby cable. This is the one that keeps the signal, let's say, permanent, from the memory of the radio stations, etc
2:58
The settings. That one is always energized. And this is the positive of the switch that sends power when the radio, when you turn the key
3:12
So that's it. Let's go to the other connectors that are left
3:17
Oh, I forgot to talk about that on this branch. This one doesn't have it on this branch, but there are others that usually have a dark blue cable that says Ant Power, which is to connect
3:31
Let's say, electric antennas are also signal amplifiers for antennas, that energizes it when the radio is turned on
3:38
that cable sends a signal it sends 12v and with that you can keep an electric antenna energized
3:47
if you need to raise it or also for signal amplifiers like this one for example this is a
3:53
signal amplifier uh in another video i'll show you how to connect it but this one is also connected
4:00
here to the iso and goes to the antenna and this one goes to the power okay i already explained it
4:06
to you. I'll leave the link below in the description in case you need one of these
4:12
a decimal amplifier, and I'll also leave you the shelf one. Let's go with the other cables. This one doesn't have one in these branches either
4:24
There's one called the AMP AMP, which is to send the signal if you have a subwoofer or an amplifier
4:29
apart from the radio. That sends the signal to it, so when the radio turns on
4:35
it will send the signal so that the amplifier turns on too. That's it
4:44
Okay, here we can see the USB cables go into these two connectors
4:51
Android radios usually have two USB ports and these go connected here
4:56
It impossible to get them wrong because they both have different connectors One is 6 and the other is pin You see 6 pins here and 4 pins here so it impossible to get them wrong
5:11
Let's go to the other connectors. Here on these cables we can find the auxiliary outputs
5:20
which at the bottom are the L and R audio outs for both channels to connect an amplifier
5:25
it could be an amplifier or a subwoofer the subwoofer can be connected to this or to the
5:33
green cable people always ask me which one to use if your subwoofer has a green cable you can
5:41
use the green cable there are some that have both and if it has both it has l and r audio it uses this
5:49
and it doesn't matter in either case. If it's subwoofer, if it has both modes, it can use either
5:57
one. If it's an amplifier, your radio speakers have an external amplifier connected to the
6:03
amplifier built into the radio, it uses this for logical reasons. Or here are the two channels
6:09
Here, on the other hand, it's only designed so that the low frequencies pass through here and
6:14
go to the subwoofer. That's it. Here you have another connector, which is the external microphone
6:21
connector. You can connect an external microphone, leave it closer to your face, let's say, so that
6:28
you can be heard better when you make hands-free calls. That's it. Here is a CBS in 2 output
6:38
which you can use to connect a front camera. The rear camera goes to another connector that I'll explain to you later
6:48
And this is a video out, a video output. For example, if you want to connect a second screen, you can connect it here
7:00
This branch here has the signal for the amplifier, to send the signal so that the amplifier in the background turns on
7:08
In some branches it is connected here and in others it can go here
7:13
You can connect it to either one. This radio, this branch comes with this option to connect a SIM because this radio has the possibility of putting a cellular chip so that the radio has direct internet
7:29
It is or you can make phone calls from the same radio That it The camera where does the reverse camera go
7:43
The reverse camera goes to this connector that has the RCA that sends the video signal
7:51
and that together with this makes it possible for the camera to be seen
7:56
This is already connected at one end. Here we are going to make the camera focus well
8:08
One end is connected, it is connected here and the other end obviously goes to the little
8:13
camera that is here. The little camera is connected here
8:22
But this little camera has to have power. And where does it get it from
8:27
From the positive of the vehicle's reverse light. So, with this extension, you connect the positive to the vehicle's reverse light and you can
8:38
connect the negative with a chassis screw. In other words, chassis means connecting it to any metal part
8:46
It is not necessary to connect it to the negative of the reverse light
8:50
So instead of cutting two cables, you only cut one and secure it with a small screw
8:56
You can then put a washer on it so that it is better secured and so that it does not
9:00
get cut or come off. This cable, in turn, the positive has to be connected to this positive here
9:12
So, they are connected together and send the signal. In addition to powering the camera, it will travel through this cable to the other end
9:24
This other end is the one that is connected here to the pink cable of the branch
9:29
So, connecting those two, connecting the RCA of the cable and connecting the power to the
9:37
camera and sending the power through this cable to reach the radio
9:43
The camera will continue working fine. If you have any questions, you can write them in the comments
