What brand is the navigation and reversing image added by Mercedes-Benz 4S store?

What you sent is not the original film, so it doesn't matter what brand. Try it a few times and it will be sensitive and clear. Navigation has no original factory, so it can be used. Whether it's 4S or outside store, it's basically the cheapest. There are many brands in the market, and 4S is also randomly selected. If you want to use it well, you still have to spend more money on it. But there may be something wrong with the original factory, not something brought by the original factory, and there is no guarantee. It depends on luck. You can use it temporarily and then solve the problem. There is no other way.
