Same issue
I have same exact phone and a Kenwood DDX719 head unit...bluetooth sounds terrible ...when I took it back to installed...they called Kenwood and they had no answer....when I look up phone on my radio model ....galaxy 2 is not on the list...it's works...phone book ect..just people say it sounds terrible. I am hoping Kenwood has an update for phone...it's not like that's an uncommon phone. Let me know if u find any answers.
