Hey guys, so my promaster I just bought has the old, crappy default radio in it (not the uconnect, it didnt have a screen at all). So my dad and i found an old backup cam and the default Uconnect radio/screen at a junkyard and ordered them for $150ish. Anyways, long story short, I was excited because i would hopefully be able to play the thing from my phone soon.... Little did I realize that it seems to ONLY have bluetooth! Yes, I can play from bluetooth, but the audio quality is worse and itll be frustrating when I have other people in the car who want to play but not hook up their device via bluetooth. Any way around this? Does anyone have a way to play over AUX or USB?
