Hey guys. Question for you all. My factory Bose system stopped working so I'm trying to replace it with another factory one. However whenever I call different places for it if they ask the manufacture date and I've come across some online as well. Does the manufacture date matter? I thought. As long as about was 6 disc and powered by Bose it was the same for years 08-2011. I don't wanna buy something online n then it is not the right one. Thanks for all the help in advance
