I am really hoping someone can recommend a quality plug that looks near-factory. Amazon is full of cheap ones that I don't think look all that great.
I did use the Metra adapter. It was a super tight fit and I am not sure I could get the radio back out of it if I needed to. I forced it in from the back. It made it about half way before it got stuck. I set it out in the hot sun for about half an hour, set it face down on a towel on my driveway, pressed with some weight behind it and it seated the rest of the way. I was waiting on it to crack but it did not. I have seen posts where some people trimmed the Metra adapter but I really didn't want to do that.
