Hello! I have had a Volvo V70 MJ2010 since almost 1 1/2 WEEKS (show follows in better weather :-D) This one has “only” the completely sufficient standard music system. However, I wonder if retrofitting is so easy. The radio has an Aux input. I could imagine e.g. the Kenwood KOS210. In doing so, you can feed the signal via the AUX or via the antenna. But.. does the radio have a simple, normal antenna plug? What possibilities do you have? So far installed? Greetings, Holger
