Company and support are the best, helping to choose the right one and correcting my mistake ordering. Product with audi AMI/Concert system is working well. I’m using it with iphone and works properly with apple music, but spotify streaming has wery low sound quality and original dash controls isn’t working, because skipping song by next button opens apple music player and song info on display does not changes, when skip songs on my phone. But apple music player has pretty good sound quality and almost everything works from controls on car’s radio. Great product and great support.
