Hello and greetings to everyone. I just joined today and would like any assistance I can get on this topic. I have a 2010glk 3504matic and a 2015 Glk350 4matic. The 2010 came with H/K speakers and the Logic 7 option but the 2015 didn't, it just came with the stock speakers. Is it possible to swap the two? Would I need any modifications? Would the Logic 7 option come up on my display if I do succeed to swap them. What and what do I need to know. I'll appreciate any information I can get. Thanks!
