I tried all of the above and nothing works, It keeps telling me when safe to check the usb connection. I used to have the logo on my car screen, but no longer do Help

I just bought a 2018honda accord. My apple car play was working fine with my iphone 6s. Just this past week I lost the icon for apple play on my car screen . I click on settings and smartphone then apple play then connect. I keep getting the message, When safe check your usb connection. Every thing is fine. I tried changing the wires and restarting my phone. I have car play enabled on my phone. I can't figure out why it won't connect. Nothing is letting it connect. Please Help. Maybe I should delete my phone from my car and re pair it. Or maybe delete my car from apple carplay on my phone and reinstall? I just don't know HELP
