I bought a 2015 spark this last year, and have recently upgraded my phone to the iPhone XR. with that being said, I don’t have a USB input to my radio. Just the aux, which means that I cannot charge my phone while I listen to music. I wanted to try to swap out my aux for usb. I don’t have a large amount of knowledge of wiring, and electrical. But I’m good at learning how to do just about anything. Any suggestions from anyone? Part suggestions? I’ve found a couple replacement USB sockets for my year car. BUT I’m not sure if that will work with the wiring I have, or if I’ll have to rewire someth
