Well guys, we know the positives.
Reading the reviews, we replaced the crappy old one in the Nissan Micra.
The sound improved dramatically, which generally doesn't bother me, I have no expectations.
The phone connects easily, although there is a slight delay in speech, I'll see, it's still early.
The reception of stations did not improve, although it is good, I would say, the menu is not very easy and the buttons are very small.
However, the sound system has a huge downside that if I knew, I wouldn't buy it and I wouldn't recommend it to anyone to buy it. YOU CAN'T SEE ANYTHING WHEN IT'S SUNNY. Its screen is made for cloudy days or night, with the brightness at its maximum. Also, the screen has reflections that worsen the situation. I will call the service to see if there is a problem, although I don't think so. I don't know if the angle or the location plays a role, but in my car, I don't have a screen during the day. Since I was looking to see if there is any stuck film and they didn't remove it. If something changes, I will come back and talk about CD, USB, etc.
May 9, 2022. The CD plays exceptionally well, the USB takes a long time to read it initially, then everything is fine. I got used to the menu a bit, after finding detailed instructions online. However, if it's sunny, you can't see anything, as you can see from one of the two photos, it's open at maximum brightness.

It revived the sound of my car and made me realize that I also need to change the speakers. I had never taken out/put in a radio before, so I was anxious if I would be able to do it. In the end, it turned out to be much easier than I thought. A simple video on YouTube showed me how to remove the factory radio of my car, and another one showed me how to install this specific radio. It was truly a surprisingly easy process.

The CDs are read normally, the Bluetooth works perfectly fine, both for music and calls. The sound quality during calls is good, as well as the microphone, with the only headache being where to place it so that you can be heard without interference from the wind coming through an open window. Keep in mind that the microphone is essentially a long cable that connects behind the radio, so it's good to think about where you will place it before installing the radio, in order to find the route there without the cable being in your way. One suggestion I found is in front of the dashboard and behind the steering wheel, so that you can be heard and the sound is "isolated" from the wind, but personally, it didn't work for me as the other passengers couldn't hear me.

One thing that is not particularly convenient is its small buttons, as it makes it difficult to use. Its menu is simple, concise, and straightforward.

Keep in mind that you may need an adapter for the radio antenna. I needed an ISO to DIN adapter, which cost just under 2 euros.

Informally, at the moment, the control buttons on the steering wheel do not work for me, and the radio takes a few minutes after turning off the engine to turn off itself, consuming battery. The latter can be easily solved by removing the radio's "plate". After a little searching, I saw that the purchase of a small adapter is recommended, which somehow allows communication between the radio and the steering wheel and sometimes solves the battery drain problem on its own, but it costs over 80 euros, so no thanks.

One issue I have noticed with the Bluetooth is that sometimes it gets deactivated by the radio when the latter is turned off, and when I turn it on, I have to go to the settings to reactivate it.

Another minor issue, more for your information than a constant problem, is the radio's mobile application. The use of the application is necessary for some reason, either for Bluetooth connection or for USB connection, and we can only choose one of the two. The application itself didn't seem anything special to me, so I prefer to use the mobile's player instead.

I bought it to replace an old JVC that had given up (it would only play the right side or the left side). The installation is standard and easy, the difficulty lies in the console of each car. At first, the menu was a bit difficult to use (compared to the simple JVC), but once you get used to it, everything becomes very easy. It dramatically changed my sound, with the same speakers I had before. Suddenly, I had bass, I had proper treble, and no distortion at normal volume levels.

It connects instantly via Bluetooth and at least on my device, it plays whatever I put from my phone immediately. By the way, my phone is an old LG from 2014.

The USB also works almost instantly, with a normal delay of 1-2 seconds on the first play (I have around 300 songs, so about 30 albums in total). Within the album folder, the songs change immediately, while switching between folders has a delay of 1-2 seconds.

I connected a subwoofer for testing, and enabling/disabling it is very easy through the menu. The factory EQs are decent for every taste. It also has some menu settings that "enhance" the lows and highs for those who want more than their regular speakers. CDs play normally, I tested both genuine and copied ones that used to get stuck in the JVC. They play fine.

I can't comment on the microphone included in the set and call quality because I haven't used them (and probably won't).

Overall, it seems like a decent device for its price, and although I haven't encountered any issues like with previous ones, I did have a problem with the screen. Somehow, moisture got inside (either at the factory or during transportation), possibly because the screen insulation is not as it should be. As a result, for a few days that I had it in the car, I saw moisture stains (like bubbles) inside the screen when the sun hit it directly. I took it for replacement under warranty, had some issues with the store that would handle the warranty, but it was eventually replaced by the store where I bought it. However, there are still some traces of moisture on this front panel. Well, I thought since it works, it doesn't matter (I said something else, but I'll censor it), I had already been without sound for 1.5 months, so I put it back on and it still works.

Easy installation, includes the adapter for connection, plug and play in 20 minutes with coffee in hand. In combination with 4 Pioneer TS-R1350S, clearly better sound than factory ones but it doesn't "hit" too hard either... Decent volume with respectable quality (without distortions exceeding the "look at me, I'm a show-off at the traffic light" limit). Particularly pleasant surprise is the ease of connectivity and Bluetooth call quality, simple and seamless without unnecessary annoying actions. It hasn't presented any connectivity and responsiveness issues even after 1 month. It seems to work fine on an 8gb usb 2.0, we haven't had any mishaps yet... The menu is a bit of a hassle and lacks shortcuts, for simple options sometimes you have to dig quite a bit. Many settings to tailor it to your needs (and your speakers...). A reliable source with ease of everyday use, with many options (personally I would have liked it even simpler), excellent connectivity and call quality that will give some volume to your speakers without crazy distortions even at maximum level.
