Yeah these will fit standard double din’s fine, but I did have to trim my bezel as mentioned to fit the stereo height, was easy to do.
I’m using an older Pioneer and it works okay, but kinda old. I don’t like the push button volume though, I do have a remote for it I keep on the seat when listening to stuff so I can change the volume easier, otherwise it's a pain to adjust while actually driving. I have a backup camera as well, but have not installed it yet. Most head units these days should be able to run a backup camera, just have to check the features / specs / camera requirements if any. My dash kit was just a cheap one from ebay that included the harness for under $16 total, was way cheaper than even Walmart, and they didn't have what I needed in stock anyway.
