Simply pioneer!!!
It doesn't have many reviews and I was in a dilemma whether to buy another model from the company, but it's better that I ended up buying this one and speaking from its value for money. I believe that for this price, you can't find anything better and it compares even with much more expensive ones! Today I installed it in my car and I have noticed a huge difference compared to the factory one I had. In my car, I have 2 6.5'' Hertz speakers, 2 tweeters, and 2 10'' rear speakers, obviously needing an amplifier, but I installed them like this with the stock radio. As soon as I turned on the radio, I noticed a significant improvement - they play louder, clearer, and better than before when I had a Bluetooth adapter and experienced interference. Now, I have none of those issues, it plays crystal clear and produces a very nice sound. The menu, although it's my first day, is easy for me and I have already learned it, I can say that it provides various settings that satisfy me enough. I hope I helped and I will come back with a new comment in the future, but I don't expect anything negative because this radio is truly quality. Get it without hesitation, don't bother with anything else and don't have doubts like me, you won't regret it once you install it.

Since it has been a month, I can say that I have a complete opinion and there are indeed some negatives!
-During the day, you can hardly see anything and the brightness doesn't increase.
-I don't know if I got a defective product, but the knob gets stuck and when I try to make an adjustment, it jumps to 5 other settings by itself.
-The aux cuts off the sound a lot, I don't know if it's because of the cable I used.
-The max volume is at 62 and you have to turn it for an hour to increase the volume.

Now, the positives are that it has many menu settings and it's easy to use, it has been quite convenient for me, I must say.
With the USB stick, it doesn't face any problems and it plays quite clearly and loudly without any issues.
If I didn't have the problem with the knob, I wouldn't mind the other things so much, but it has annoyed me quite a bit and I hope the store replaces it because I see myself breaking it as it's quite frustrating when it gets stuck, especially while driving.
That's all from me and that's why I will give it 3 stars because it disappointed me with the mentioned issues. Hopefully, it was just a defective device and it will be replaced.

After the last update I made, I have to say the following: if someone doesn't want to listen to loud music and just wants a simple radio, they should get it. For someone who wants to even create a small sound system and save money for something better, I returned the Pioneer and bought one from Alpine, and the difference is huge - the speakers play cleaner, louder, with no distortion at maximum volume, it's like I have them connected to an amplifier, really! I hope I helped some people and as for the knob on the Pioneer, I just happened to get a defective piece, but for someone who doesn't want anything extravagant and just wants to upgrade from an old one to something newer, I recommend it for this price, but only up to that point.
