Hello, I have the following question, which could not be answered even after a research in the forum. I drive a Sandero, built in 2010. He has the blue-point radio ex factory, mp3-capable and 4 loudspeakers, no audio input and also no radio remote control. I would like to buy a new radio, because of the missing USB port, but the speakers continue to use. Does anyone know what these are (performance features)? What properties must the new radio have to mi t to harmonize the boxes? Apart from 4 x 15 W I am not aware of anything, also inquiries with Dacia or. rereading in the operating instructions did not yield anything. Thank you. MfG
