About a month ago I replaced the battery in my 2015 Elantra SE. when the new battery was installed, I lost ONLY audio to ONLY XM Radio. I was just listening to it before I replaced the battery. FM and AM radio works fine. Sat info pops up on each station. Hyundai has just told me that I now have to have BluLink in order for my Satellite Radio to work again. Problem is, my Elantra is pretty basic. I do not have a fancy new media touch screen. My screen only displays radio station info. I have a MEDIA button, but nothing is there when I select. Please help if you know anything.
