have the Krämer KR-747 now for several months and am absolutely happy with it.
Personally, I have a small 8GB USB Stick drangehangen me, so I've had enough of music. It can be read and played all playlists, folders, titles without problems. Equalizer is naturally present, clearly should be standard.
The navigation function is impeccable, until now I have always achieved my goal.
Furthermore, I still have to install a rear-view camera and the image is given by the instrument very well again.
5 stars for a quick Navilösung with good sound!
