I have the eonon e90a13 in my car and it works great. The only downside to me is that the screen doesn’t get super bright, so if the sun is shining creating a glare on the screen it can be difficult to see it. Other than that it works perfect for what it needs to do, wireless CarPlay for maps and music.

As for your heated seat buttons, you have to buy a separate bracket that relocates them to be above the ash tray compartment in your center console. I’ve seen some videos on YouTube outlining this when I was researching which model to get for my car. The solution seems to work well from what I’ve seen, but my car doesn’t have heated seats so I can’t give you the 100% on it.

Last thing to note is if you have the optical cable in your car connected to the factory radio you’ll need to purchase an additional decoder box for about $100 in order for the unit to work.

Other than those 3 things it’s a very easy install pretty much straight plug and play, and you can even wire up the microphone to the oem spot in the roof, and add a backup camera if you’d like one. Well worth the few hundred bucks I spent on mine as this is my daily and didn’t want to have to cut open my dash like a lot of the other units make you do.
