Possible Positiva / negatives have already been dealt with in other reviews, so here only the subjectively important for me again:
+ No CD drive (thus the vehicle is cleaned up and the question of MP3 capability does not arise)
+ Very simple installation
+ Good compatibility with the vehicle and the mobile phone
+ Good facilities at ports and functions
Understandable + Installation and Operation Manual
+ First-class price / performance ratio
- Non-changeable backlight color
- Cover the front connectors can not be closed with micro USB stick inserted
- The designation of the preset equalizer profiles is meaningless and therefore unhelpful
To sum up, simple installation and setup (about 20 to 40 minutes, depending on personal ability), good features, clean working hands-free, and all at a very reasonable price.
