I don’t even know which radio was originally installed on me – the previous owner replaced it with a DIN part of Sony. There are also only the four broadband(?) loudspeakers in the doors. So: Vanilla equipment of the MJ 1996. Since the Sony thing is annoying (ugly, unergonomic, radio is not working properly, and then this disgusting shut-down-pling sound!), I got a SC805 suitable in black. With operating instructions and code. Now I guess: It will not be reic Presumably, an amplifier has to be fitted, the more suitable eight loudspeakers have to be in doors, dashboard and D-pillars, and possibly the wiring has to be adjusted. Who has done this before and can give me hints? Additional question: Is there an interface with which one can realize an Aux input and/or an MP3/WMA player (from USB stick or so)?
