I upgraded to the S4 from an older Samsung phone that played music through the radio perfectly. According to other posts, my 2012 Cruze will not recognize the S4......and after trying myself, I found it to be true. Are there any products out there that will act as an interface between the radio and S4? I want to plug it in via the USB port and NOT via Bluetooth. The audio quality of Bluetooth SUX. Or does anyone know of an aftermarket radio that will work with the S4/USB combo?
