Need help please. I have searched but always leads me to the XF (that upgrade is in the works). Upgraded my 2011 XJL North American Spec 5.0L Naturally Aspirated to the B&W System. All speakers and amp. I did not have SDD at the time so enjoyed 2 years of better sound without full capabilities on the touch screen. I finally got SDD (newbie) and tried to update the Audio Module. It was not successful and now have no sound. I think SDD tried to load the as built file on the upgraded amp. Please assist or point me to a valid XJ Thread. I appreciate any help I can get.
Bowers and Wilkins upgrade (Help)!
