Black screen, changed cable and did everything suggested in other forums. My head unit is a Pioneer 2550nex and works with my S21 Ultra and S20FE. I couldn't live without AA in my car so I returned the S22 Ultra. Glad I didn't send in my S21Utra trade as yet.</P> Fri, 25 Feb 2022 15:24:19 GMT Barry B 2022-02-25T15:24:19Z
