Radio, AUX and a few more questions

Hello Schwedengemeinde, I have been proud owner of a V50 2.4 since last week. The decision to get me a Volvo again was not difficult for me, because I had a V40 years ago and was very satisfied with it. Now it turned out in the short term that this should become my 2006. And as satisfied as I am, so much I lack the opportunity to continue to use my meanwhile beloved Spotify. I spent almost the whole weekend I can’t tell you which entertainment system I have in it. The only thing I know is that I don’t have an AUX socket behind the waterfall or in the armrest. On the radio, too, the button is labeled with CD instead of MODE. Now there seems to be different ways to connect external peripherals or to put them into operation. One of them is a guide on how to work on the internet. The circuit board of the radio can solder an AUX socket directly. I would also like to do that, but unfortunately this is not complete, because the pictures are missing. And the author CROSSIE seems to have been active in a forum for the last time in 2014. Next I found these adapters: –> Klinke These adapters are available in several versions such as Klinke, Chinch or Bluetooth. But everyone says that the CD/MODE button AUX has to be selectable. If not, here the Freu has to be Now my question: Can any radio be unlocked on AUX, even if only CD is on the button? And what is the fun when the friend lets his apprentice play a software? Last but not least, I also found a box that emulates a CD changer. To my questions at this point: Can one theoretically disconnect the CD drive and connect this box for it (I don’t use any CDs anymore nowadays)? Is there a connection by default? uss for a changer, and if so, does this also have to be unlocked again by the friendly? The variant of Bluepower is probably the most elegant, but if we are honest, also not cheap. Maybe you have some ideas and tips for me…
