Etc. For those interested in audio books is the listening experience, however limited because the device but continues during operation via USB or SD to the point at which it was switched off, but there are no navigation options within a track. This is very annoying when tracks of more than three minutes in length, for example if you want to rewind time a little. That's why I play audio books via its own MP3 player via the jack input from (cable for connection is, 3.5 mm jack), but in this case you will hear a slight noise. Who thinks he can while the MP3 player hanging for charging to the USB port of the device, I have to disappoint you: Once there a device is found, it will be selected as the source. In my demand at Mumbi came out that the device complies with the following play order: SD, USB, jack.
Also, the device sends no signal when playing from a USB stick when the jack still drinsteckt.
What I have noticed negative: The FM transmitter has no way to save a preset broadcast channel, or to use the last selected. With me he jumps when turning increasingly to the standard 96.0 Mhz back, but I'm lucky on this frequency is found in me near no station.
Buy recommendation: For all those who want nothing to change in your car or can.
A car radio with USB support and good navigation options is at much higher sound quality significantly easier to use (who as I used an iPod, should make sure that the device is the car radio is usually confused with the playback order IPod compatible, because the title does not are stored necessarily in a sensible order on the iPod).
Conclusion: As a transitional or temporary solution highly recommended, in the long run, however, a car radio comfortable (and in some cases there is really cheap offers).
