So I have a 2016 pilot ex-l. I bought a radio unit out of an ‘18, installed it and it starts up with the Honda logo then goes black screen, I can’t get anything out of it. So then I bought a radio out of a ‘17 but the USBs would not connect. Did I get 2 lemons or am I missing something here. It seems everyone is having good luck with this and I’m falling short somewhere..
