Connecting Pioneer DEH-1800UB Radio to Audi a3 8l Attraction 2001 - Steps?

Hello and welcome. I have a car Audi a3 8l attraction 2001. 1.6 benz. I bought the car without a factory radio. I bought a Pioneer DEH-1800UB radio, but I don't know how to connect it to my car. I also bought an adapter (ISO adapter), but I still do not know how to connect it ... I am asking for some tips. Add photos:

From the first photo you connect the orange cube to the right cube from photo 3. The black cube from the first photo (the one on the left) to the left cube from the third photo. You do not connect the last cube at all because it is probably some external display, maybe an on-board computer. Otherwise, these cubes cannot be attached This adapter from the second photo is rather redundant.

You need an adapter to connect the antenna. In a norauto shop, media markt etc. will know what it is about. Exactly something like this: https://mediamarkt.pl/rtv-i-telewizory/adapte...CHdRt9Af1GdrE9GuG1GUAAFuAF1GUAAFUAF1GUAAFUAF1

If you have speakers in the back and sub then you will have a little more fun. Because the 3rd cube is responsible for that. I found somewhere on a forum:
"Hello,
Today I changed the radio chorus II, audi 2002 3d on the Nokia system for the pioneer radio.
At the beginning, I connected only the iso cubes, only the speakers in the front worked for me.
I started searching the forum but unfortunately didn't encounter a problem like mine.
I have three cubes 2 ISO 1 wide C1.
From the C1 cube I connected the black and white cable to the remote control system on the radio, the white and blue cable - this is the power supply for the amplifier.
Then the blue cables and one of the two connected together I connect the green stripe and the green +/- right speaker and brown and red, and one of the two connected together I connect the purple stripe and the purple one.
I twist the ball, the radio turns on and the amplifier plays all the speakers and sub. "

You can also purchase such an adapter. You attach it to the ankles of what's in the car (black double plug and the one on the right in the photo) and connect what will remain (2 cubes on the left) to the radio, as I wrote above.

I burned these cubes as you wrote, but unfortunately nothing happens ... I add photos.
And I will worry about the sub later when I connect.

Fuses check and turn the key: p there is no other option to connect it.

The key is twisted, it's obvious . And which fuse is responsible for the radio?

You have to look in the manual. On the net you will find. Apparently there is no voltage there because with such a connection it should turn on normally. If the fuses are ok, the case will get complicated because you will have to pull new cables. The old radio worked? It's best to get a 12v bulb, some led or something like that and see if there is electricity there.

I bought a car without a radio, so I don't know if it worked. The fuses look good so I don't know what else to do ...

You have to somehow check if there is electricity there. You can't think of anything else. You can use the meter as you have, and if not, make a sample of the LED diode or some 12v bulbs. The current must be on + 12v and on memory according to this scheme (you have a black cube smaller) https://goo.gl/images/cXfRUR

So far I have no way to check if there is electricity. But I also have a question, should there be no more cables in the two cubes that come out of the car (brown and black)? Together I only have seven (4 and 3).

See the diagram above and you will have the answer. In Audi, only the front speakers are connected to the radio, therefore there are 4 cables in the orange cube. The empty ones would be for the rear speakers, but in this car they are powered by an external amplifier that connects to the radio using this 3 cube.

And as for the black ISO cube, there is not only a remote, but because this cable is also moved to this large cube, so that the amplifier turns on with the radio. If you want to connect an additional amplifier, then you need to connect the blue cable to the remote in the amplifier (the blue and white cable coming straight from the radio, described as remote). But as you have, there are approx. 3 power cables in one cube (+ 12v, ignition switch and ground) and 4 cables in the other cube (+ and - from the front speakers).

If you have the option, connect this radio to someone in the car because maybe it is simply damaged. Or take some cable and connect this radio briefly directly to the battery. + 12v and ignition switch to plus battery, and mass to minus.

The red and yellow cable is not disconnected from time to time on this cable, what was for the radio? Because there are connectors so fast.

Fuse 42 on the side is responsible for the radio

@vortuss will be a small problem because your A3 has a radio installation on CAN
In the black power plug where there are 3 cables, you only have the power supply and the K diagnostic line

To power this radio, you need to connect the red and yellow wires in the radio cables. After this treatment, it should light up.

In the brown iso cube from the car you only have the front speakers. If you connect to the radio, they should play.

If you want the back to play, look for: Adapter for the active BOSE AUDI (ISO) system


It would be best to install an ori radio with an audi np concert there, because others will not have ignition logic, adjustable backlight and if you have a meter with FIS, you will have RDS on it.

In fact, it is probably as Heinzek writes. Here is a description of the ISO cube from Audi http://elektron.pol.lublin.pl/users/djlj24/studio24/kable/isooem.htm

So the only option is to connect the red and yellow cables that go from the radio to each other and connect it to the plumb marked as + 12v constant.

And if you want to turn on with a key, you have to redo the installations. I think you could take electricity from a lighter or other device that turns on with the key. Then you connect the cable from this lighter to the red cable, and you connect the yellow cable to the memory according to this ISO cube diagram, which I sent in the previous post.

I connected these cables and the radio blinks, I only connect the antenna and it will be ok.
Thank you very much for your help!

Connect this antenna amplifier to the blue cable that comes out of the radio bundle.

Everything is nice, beautiful, I just have a question.
Can I do something to make the rear speakers + sub play? Will I do without an adapter or will I have to buy it?

Edit: And how to put this radio in this pocket? It practically goes to max 3/4 and something is still blocked ... and nothing sticks out there, the cables also do not bother

I gave a description at the top, but I don't know if it will work. Buy an adapter and head. When it comes to insertion, they usually just block the cables. Maybe press the iso cube down because it can block: p

It all depends on your skills. You buy the adapter and connect it.

Without the adapter, you have to do some research.


As you can see, this is how the cubes in your car are connected (almost, because you do not have the BOSE system)
To play the back, you need to connect a total of 4 pins. You are only interested in the ISO C1 cube and RCA output from the radio + blue cable for turning on the amplifier.

So you need a short cable on one end with phono terminals that you connect to the RCA outputs on the radio. The cables will end with a "hot" white conductor (left channel) and a braid (ground) and a "hot" red conductor (right channel) and a braid (ground)
You connect the masses together and connect the C1 cubes to pin 3
Red wire to pin 2
White conductor to pin 1

You connect the blue cable from the radio with the connected amplifier to the antenna to pin 6 of the ISO C1 cube.

Then the rear will play

I will probably give it a break for now, I will buy this adapter in the future.

But the matches are still with the insertion of the radio to the end ... still a few cm is left and does not go any further, I tried to put the cables in but it does nothing ... and as it sticks out it looks independently

I'm sending a photo

A tough case. Maybe something in the back folds up and gets stuck. This is the advantage of a non-cd radio that is much shorter: p

Hello, it's me again, the radio is plugged in, but I have another problem. I played around and tried to connect without adapter, rear + sub speakers. However, the effect is that only the front + subwoofer works, the rear is not. I soldered the chinche as it was given earlier, but the back does not sound. Any ideas? Add photos.
Regards.

Can anyone help?

You have to squeeze the bottom and top plates of the radio, then you should get all of it.

Hello, I would like to connect to the topic, namely, I would like to connect a non-factory radio to the A3 8l 2000 so that it works + sub I bought a module for it and the module itself has an unsupported black cable (ground) where to connect it? Can I go ahead and connect it to the power cube to the ground that is there?

Can anyone tell me what this cable is for a3 8l 2002 it is a subower

Added after 5 [minutes]:

One more thing from the radio, apart from the cubes, a black cable comes out, rather the original goes as if I was touching the ventilation 😁 what could it be

Because this radio is not original, you must have the appropriate adapters to connect it.

you need an adapter, or you can run the cables to the rear speakers directly from the radio.
