Hi all! I was wondering if you could help figure out my problem! In my 2014 Chevy Spark, when I shift into reverse, it shows a service rear camera screen...and I don’t have a back up camera in my car! Also the volume buttons on my steering wheel do not work anymore (and they were working a day ago), and i am missing the temperature display on the screen. Is this an easy fix? Thanks for your time!
