qube 3570 Report post Posted November 10, 2017 I have a E91 2005 that came with the older stereo and have purchased this newer one to get USB etc functions. Plugged it in and get no sound. Google shows that its not that straight forward but not 100% clear what needs to be done. Any one able to shine some light in plain english or help with the retrofit? photos of the old vs new unit Quote Share this post Link to post Share on other sites
