Negatives: 1. Radio reception is appalling. Continuous crackling, rushing and complete Tonabschaltungen make radio listening unbearable. 2. Actually, the worst problem because the Tristan pulls slowly but surely the car battery empty. Have it connected to continuous voltage, otherwise the radio station and Toneistelllungen are always at Schlüsselabziehen away. But after that the car does not start anymore soon. Then have an extra switch between built and therefore live the way the stations are respectively the bass and treble adjustment 3. The manual is ridiculous. There usually is only in it what you know anyway. For example, playing music: Press the Play button (-) ... Ok) Just what you want to know, such as the setting of the random generator is working or the radio carries on there during MP3 playback where it stopped ... None , I have it somehow hinbekommen on FB but confusing. Can the way but no longer understand. At least this setting is retained when Spannungabschalten. 4.For the volume adjustment on the touch panel requires some skill. I have it now relatively well under control. Courageously with your finger on it and circle without letting go, otherwise react the other touch keys. By the way thereof and there was nothing in the instructions.
Positives: The playback from USB, SD card and CD / DVD is good. This applies to audio, MP3 and MPEG. MP4 are not played for any reason and AVIs have dropouts. The screen has a very good resolution.
Conclusion: The shortcomings are inexcusable. Radio listening is the alpha and omega and a car radio may the battery never leersaugen! It is just an immature China product. On the market thrown with many flaws. Since the low price is no good.
Can not recommend it therefore.
