After the expansion of the old radio was a bit difficult, the installation of the new radio was almost easy. There was a small adapter and after some back and forth we also knew that we just had to switch to permanent positive, so that not always lose when you turn off the radio again all settings.
The rest of the device is simple, station search (the search works even with super old-Opel-typical half extended antenna), press two seconds to place button on which the station is to be stored, ready.
And the sound is unexpectedly good. By that I honestly would not expect, because what the radio can already change size when the rest is given? But in fact the sound pretty good and above all, the device has power, can be really loud music heard.
In addition to the radio and the usual CD player (the one even the titles of the songs displaying when playing and also remembers where you left off and re-used there, when turning it back) can also music via USB Stick and even play by its own smartphone, which then probably is the next level of playback media.
Only with spontaneous reduction of the volume (Mute) to do the radio and I felt very heavy. I'm used to it, as easy to press the volume knob but unfortunately you end up with it in the advanced settings.
If you turn the car off and the detachable front element is still completely on the attitude, a warning signal sounds. When it losklickt, but does not decrease, the signal does not come. Removing and reinserting the control element is simple and works just fine with one hand.
Overall, a visually appealing device that sound-wise right so expect and even in a really old car.
