I will speak very briefly on my experience with the device are limited, since everything else can be abgefrat to technical details on the internet.
The radio I have now been a few weeks and could not complain about me.
The installation designed with prior knowledge (which you should have) as simple, as well as the expansion .... it is a guidance and the right tools at.
The radio has a lot of options as far as the sound, as well as dim function and other useful stuff sometimes.
I use it mainly to listen to MP3 albums, until now, I had no problems as regards the blanks.
A selling point was the front AUX input for me, here you can with a cable (not supplied) everything from iPod to laptop.
A mute button, there are not, unfortunately, but who needs that when you have a knob for volume adjustment.
Display is clearly readable, even in direct sunlight.
The reunification in the device is simple, it should be realized that the features described in this document are limited in each case to the Radio mode (Tuner / Aux / CD ...). That is in CD mode, you can make any settings on the volume level of the AUX input must they only change to the AUX mode.
For a little more money you can I believe the same model with additional front USB port purchase.
As for the lines of the device in terms of "loud" music I do not know, have only the standard speakers in the dashboard angechlossen.
Have fun with it :)
