Overall I'm happy with it, but some functions don't work. For example, standard parking sensors work, but do not work on teyes, or for example, climate control. It works on the car, but doesn’t even show on teyes

This is not the first time I buy from this manufacturer. And was always at its best, as in this case. Minor flaws and questions are resolved immediately. There are enough communication options.
After the sad experience of trying to install a similar device from another manufacturer, I was once again convinced that: they are not looking for good, good.))
Thank you. Prosperity to the firm, business success and continue to delight the consumer with good products.
