I have installed the receiver for about half a year in an Opel Corsa D. The chassis is a little tighter, because it is the 90PS diesel. And here the operation will be difficult because the software buttons on the touch screen are so small. And it does not matter whether CD, USB, radio or telephone. Also, the controls do not are not the same for USB, CD or Bluetooth, is disturbing. You get used to it, but it's just stupid. This could be solved with a software update and catch up.
Also, the device does not connect for BT audio set with the radio from the outset but is required to establish the connection only when spoken to quite a while, is annoying, but bearable.
So: If same Oberflöchen, larger buttons and improving while reading the USB Audio and BT-Audio would be via software update, the unit would get smooth 5 stars!
The radio reception and the sound are very good for me. The color settings make it easy to adjust the radio.
