Please share what programs & settings you use to convert videos/movies to play from an USB/SD on your AVIC-Z110BT/Z120BT.
I have spent some time reading threads but there isn't much information related for these two models.
I particular like Handbrake to convert videos, it's free and Windows/Mac compatible but I have not figured out what the working settings are. I have tried the conversion multiple times with different settings and non of them work.
