This touch screen is a massive upgrade from the factory stero. My camry radio got the loading screen of death, so I either had to buy another ghetto factory one or get a sweet touchscreen. Obviously this is the way to go. For starters, I am not a car guy. I have no idea how to do this stuff. But I have tools and a brain so I went at it. There is a really good YouTube video that's about 20 mins long and it's 2 dudes and they walk you through each bolt and screw. They also show in detail which wire plugs in where. I just followed along with them and in the end it all worked perfectly. The screen is super responsive, fast and looks great. It's not 4k, but I would say def 1080. The trim prices connect to the bottom with a bit of a gap as shown in the pics. Everyone seems to have that problem. It's not anything you can fix by adjusting the install. It's just manufactured wrong. But it's not noticeable at all unless your looking for it. I have a 2015 camry xse. Everything works. Steering wheel controls, backup cam, and microphone. It took a few hours for me to do it all myself. All you need is a Phillips screwdriver and a 10mm socket and your good to go. If your on the fence cause it's an off-brand Chinese radio, don't worry. It's great.
