Very, very good source, a store owner friend recommended it to me because the Pioneer sources I had did not satisfy me.
As a source, it is just right for someone who wants to install amplifiers and heavily upgrade their sound; I have this one connected to 3 amplifiers, one for the speakers, one for the horns in the doors, and one for the bass in the back (These are powerful with the use of a 3-Way Crossover where the 3 pairs of RCA outputs at the back can be adjusted separately for each frequency range, read the manual), DSP although I would have gotten one, I saw that it has DTA settings, I have adjusted them and saved myself the DSP, get it with your eyes closed!
In terms of volume, it always depends on the amplifiers (if you have any), I have set everything with DD1+, the 40Hz distorts at 32 (4.2V) and the 1KHz at 34 (1.7V) (These may vary with revisions of the source).
I will answer any questions from people who might be interested in getting it.
ALSO! I see that there is incorrect information on Skroutz, I don't know why, the mistakes I see are:
Operating System: It is not Android since it is a 1-Din source.
Detachable Front: Yes, with the button located on the bottom left of the source (It is not clearly visible in the photos, but it exists).
GPS: No, because again it is a 1-Din source.
Built-in Wi-Fi / 3G: No, because again it is a 1-Din source.
AUX: Yes, it is located under the protective cover where the USB is.
4G: No, because again it is a 1-Din source.
UPDATE: As of 04/24/2024, it has been installed in a new car with the same amplifiers, bass, horns, speakers, just with a high-output alternator, it still works perfectly, delivering incredible sound!
