[Solved] Installing Aftermarket 1DIN Radio in Audi TT MK1 with BOSE Speaker System

Hello colleagues!
I hope that I have put my topic in the appropriate section. After reading the suspended topics in several sections and categories, I decided that here would be the best place to ask for help.

Well, I got down to something that I do not have much idea about and it is impossible to do without help. I want to replace the factory radio in an Audi TT MK1 with a Chinese bought on the Internet. I treat this car as a project and if I write something, it's difficult.
The car has a BOSE speaker system and I bought an adapter without which, apparently, nothing will work.
Cables and plugs in the car look like this:

The transducer looks like this:

The new radio looks like this:

And the cable that came with the new radio:

Please give me a hint. Is it possible to combine it all into one so that it works? If you need any additional photos / videos, please write and post.
I am online all evening. If I made a cardinal error while creating a topic, please moderation not to delete the thread, fix it as soon as you let me know what is wrong.

You need to get a list of wires in this plug from the radio (look inside), in the ISO sockets, and earn at the end of this plug.

Thanks Gunslinger for the answer. I have a list of plugs, there is a sticker on the radio and in the radio manual. Can you make the rest of the message a little clearer? So far, I have connected two black plugs from the car (photo three and four) with two BLACK sockets from the adapter (I think it's called ISO?) Because only these plugs fit into these sockets. Now, as a boy's mind, I should probably cut off the two brown plugs with the adapter and connect the cables with the cables from the new radio. Only the colors are completely different. For example, for brown plugs from the adapter, no longer go red, etc ...
Do you attach a photo of the plug-in list?

There are speaker wires in the brown plug.

From the car's installation, you plug in 3 plugs into 3 adapter sockets. And the adapter plugs have 2 outputs. You either cut them off and earn money with cables from the radio, or you install sockets on the cables from the radio, which you can buy in any electronic store. You have a schedule, so you should be able to do it.

Ok gentlemen, I think I understand what's going on. For clarity, I attach an additional photo. I connected what could be connected with plugs. Otherwise, you can not do anything because only the plugs that are connected now fit into the sockets. Nothing else fits together.



So the plug marked in the photo as No. 1 (red) was not connected to anything at the time when the factory radio was in the car. Only black plugs 2 and 3 were connected to the radio (except for the mass and the antenna too). The only sockets that fit the plugs 2 and 3 are the sockets in the adapters, which I marked in the picture 4 and 5. As you can see, one socket in the adapters is black (4) the other red (5). I do not know what this means, but both car plugs are black (2 and 3).
The plug No. 1 does not fit the socket No. 5, although the color and size would indicate it, because the rail on the side of the plug is in a different place than in the socket (in the plug it is closer to one edge, in the socket in the middle).




Questions:
1. Do you think the correct plugs are connected to the correct sockets?
2. If so, it looks like I will have to cut plugs 6 and 8 because the colors of the cables from these plugs match (except for one) the colors described on the radio list. Am I right, plugs 6 and 8 to cut?
3. There is an orange / black cable in the radio list at number 20, but in my case there is only orange in plug number 6. Did they mean this cable?
4. Any other valuable tips before I start cutting, connecting and terminating cables?
I hope I'm not bothering you with my ignorance. I want to do it once myself without the help of a car electrician, so that the next time I have more or less idea how to do it myself.

Colleagues, could someone with a concept greater than me take a look at my post above? I've had everything buried for a few days and I'd like to put it back together somehow. If something is unclear in the post above, please write me completely.

So unclear is that this:

it doesn't look like this:

To be sure, give photos of plugs in the car, this adapter and what you have on the radio.

Yes, in fact, it was only a few days ago that I noticed myself that the photo of the purchased adapter differed a bit from what came in the mail. Unfortunately, to take good photos I have to wait until morning. However, the photos of the plugs in the car and the new radio with the plug and diagram are the most up-to-date, so there is no point in renewing them? Unless you want to see something that is invisible in these photos, let them know and I will try to express it better in the photos.
Thanks again for the response

Gunslinger - instead of photos I made a short video. I think that it shows what is happening much better than I could show it in the pictures, Here is the link to the recording:


The new radio looks like this:

And the cable that came with the new radio:

From what I am looking at the video, you plug in the socket adapter so that:
Adapter -> Auto
Black socket (power supply) -> Black plug
Brown (looks red here, audio) -> Brown plug (looks red here too)
Wide socket (changer) -> Wide plug
And there should be 2 plugs that should be plugged into the radio. If something does not match, then maybe something with this adapter would have to be wrong. And on the radio cable, I would earn 2 purchased ISO sockets so as not to cut the adapter.

Thanks again, buddy. I connected everything just to see if it works and it is ok. Even the reversing camera was successfully connected to the reverse gear light. Now I have to route the cables nicely through the car and terminate the connections :spoko:

One more quick question ..
Will you be able to tell me if the PC5-90 antenna adapter will be suitable for this car and radio while looking at the photos from the first post?
