Electrical Infotainment Problems of Hyundai Sonata

My infotainment unit stoped working after an update that was pushed to the car by Hyundai. My battery was beginning to show signs that it needed replacing (not cranking in the cold temps or needing a few tries to start), so I went to advance auto to have the battery replaced. Once back in the car, everything was working fine (radio with sirius xm, back up camera, navigation, android and apple car plan, the clock, everything). When I went to reset the clock, the car showed a software update was availabe and needed to be downloaded. Never before, had I seen this. So, I selected update. After 30 minutes of seeing it say downloading, it then started to say install. It gets to where it says, the radio needs to be restarted to complete the update and then gives error code 604. Now the telematics or infotainment works. I reached out to mapit, hyundia and bluelink who all say, "to bad for you, buy a new one for $1600". I did not ask for the update, I did not go looking for the update and I did not push the update to my vehicle, hyundia did and me and the other 2000 owners who are going through this should not have to pay that kind of money to have it repaired. If they new they were shutting down 3g service, then don't push the update to my car. Hyundia has admitted the issue for hyundia tusons and a few other vehicles but not for 2015 model Sonata's. So for tusons they send out 3 sd cards to fix the issue, but refuse to do so for all the cars they pushed an update to that as they called it bricked the head of the unit. I am looking for help to get this fix without me paying $1600. If hyundia recognizes the problem in some cars and not others thats an issue. One that we the public would love help addressing.
