In brief: device is not worth much. wanted to install in our caravan, so we would have FM radio and can install mp3 music nice comfortable fixed! so my idea ;-) my 32 GB card can not process it (with many other devices makes the card zero problems) so I am assuming that accepts only up to 16 GB. the radio reception sucks, and if you have a transmitter and casually pressed on the touch screen you can hear suddenly a deafening noise / screeching through the speakers, the headphones beigelgeten have such a bad sound can simultaneously equal to the ton ... is kofphörerausgang the video output, only a viedeokabel was me not participate in any more than a loader device ... I can playback options on the mp3 and video say nothing, since my sd card is not recognized. All in all, the device is not worth the money. you can prefer for 60, - buy a cheap smartphone with Android on it, which can then much more ....
