BUT:
Since I came with the same order to benefit from the expansion brackets for my OPEL CD 30 MP3, I was unfortunately only conclude that it has no place on my device. The radio flutters me though the menu the right to charge an external input is available, but unfortunately that is impossible to achieve on the connection side.
"Funny" It is so, that is on the front panel thickness and fat "CD 30 MP3", but on the nameplate on the back of MP3 at the Blaupunkt part no more talk is because now is just och "CD 30".
Well, Shit happens. Maybe I'll buy so times a CD 30 MP3 with aux :-)!
So: Always watch closely behind and have no confidence in the front view!
