I do not use this drive because of its ergonomics and certain functions:
You can not use this device without activating unintentionally certain functions such as voice recorder or ZAPPIN as the buttons are misplaced.
Best of all, the device alone decides the sound level: fitness at a "politically correct" at each start and after some playing time. As I used motorcycle, every untimely decrease the sound level must stop !!!
I used a lot the previous model, with satisfaction. This change is missed.
Good sound all the same, better than the previous version.
