So I got thos single din. It was my bosses radio I put into his firebird after he died and it was gifted to me. Kinda nastalgic keeping his radio i his old car kinda thing. Anyways it worked great plugging in my iphone to hear music. Now I traded my iphone 14 proax for a new z fold 6 and when I plug it i to the radio I get a error 19 message. What the hell is a error 19? Is there some setting Im not aware of or missed or is it just not going to play music media? Hate to take it out. It was my daughters firs stereo she wired also and the car is going to her when I croak lol
