It has neither sacred nor Osio.
It does everything and it's worth it.
I bought it for 16 euros on 15/1/21.
What do you get with 16 euros?
(Update: now they sell it for 30... no. Until 20, 25 max, OK)
I will write the main things at the beginning.
Do not use Loudness. It ruins the sound.
Use the Rock preset and you will have the best sound.
If the cables are not properly connected, it will lose the memories when you remove the car key.
More specifically:
INSTALLATION in the car in the blink of an eye.
Only one adapter (1 euro) for the antenna was needed in my car (Megane II 2003 with tunerlist source).
The damn plugs of Megane II fit perfectly into its slots.
Everything works perfectly. (except for the steering wheel controls, which are available on the market with special circuits, but they are expensive in my opinion, and on the other hand, what do you need them for with the automations that exist now and the application on the mobile?)
Of course, for aesthetic reasons only, I also bought a fascia for 9 euros, so that there is no gap around it.
The VOLUME is satisfactory... if you are not a jerk.
The person who writes below that the volume is low compared to the radio, either lowered the volume of his phone, or his mp3 files have low volume (no mastering - no compression), or a combination of both, and this happens.
I have the volume of my phone at 9/10, because I usually have well-mastered mp3s with proper compression and I don't want them to distort. For some old albums (let's say from the 70s), I turn it up to 10/10. And it is louder than the radio.
The SOUND QUALITY is excellent, although, as we know, it depends to a large extent on the speakers.
I installed Hertz DSK 130.3 in the front and Hertz DCX 130.3 in the rear, and it sounds fantastic.
It has bass and treble EQ settings, but it also has preset settings, one of which is rock, and it is great.
I do not recommend using Loudness, as it doesn't seem to do anything, and also because with the "Rock" preset, it's like having Loudness on.
Of course, it also has balance adjustment for front and rear left and right. (I prefer to adjust it 2-3 clicks to the rear speakers at low volumes for balance in the front seats)
For PHONE CALLS, it has a built-in microphone (no need for installation) and it picks up just fine according to those I talk to, but there is a slight delay in sound transmission.
I can hear them clearly and loudly from the speakers, without taking my hands off the steering wheel to increase the volume. (of course, always with closed windows when talking on Bluetooth)
I read some comments about problems with the microphone and its installation in much more expensive and branded stereos (or that you have to buy it as an extra), and I wonder.
For SETTINGS CONTROL, it also has a REMOTE CONTROL, but it is useless, as it has the APPLICATION which was automatically downloaded by scanning the instruction sheet and immediately connected to the mobile via BLUETOOTH (just like it automatically and quickly connects every time I get in the car).
Of course, I do everything from my mobile via Bluetooth. Navigation with Sygic GPS and music from my mobile with foobar2000, and everything happens automatically, I don't even need the application anymore.
So, the music plays from the mobile via Bluetooth, and when Sygic gives me directions, the music automatically lowers and I hear the directions, and then it increases again (you can hear it in the video I linked above). Also, when a call comes in, the music pauses and I hear the ringtone through the speakers, and when I hang up, the music starts playing again on its own, etc.
The Sygic GPS, after "upgrades" that have been made, is now the most useless GPS. Stay away.
The radio is great with 3 banks and 6 presets each. However, it does not have RDS.
The USB works fine. It has limited search capabilities and only through the device. I haven't explored it much though, because as I said, I don't use it, I just tried how it works.
I haven't tried the SD CARD and AUX yet, nor can I speak about its durability (okay, the buttons are Chinese, they don't need slaps, but the volume button is fine), but for its cost, I get a new one every year.
(edit after a year and a half, it still works perfectly).
How did I live without this for so long?
