To open it has a big delay. The radio doesn't catch the stations well, it's not the antenna's fault, the previous ones played just fine. The USB gets stuck and you have to take it out and put it back in for it to play. I have changed 3 USB brands but still the same, I don't recommend it

Very good value for money, it doesn't freeze, it's slow but it does what it promises, it has an easy menu, very nice design, easily connects to Android and iOS mobile phones, it just doesn't have a lot of power in the audio outputs, not that it doesn't produce sound, but it doesn't blow the speakers. However, at this price, it's a great deal

Value for money. Plug & play. Very easy connection, clean sound and nice touch screen. The mirror link was tested with an iPhone and works as it should. Whatever you see on the mobile screen is projected onto the car screen. However, be aware that mirror link is different from Apple Car Play. In mirror link mode, only the mobile screen is projected (when connected with the charging cable to the left USB port) and the sound is also heard. However, there is no possibility to operate the mobile through the screen in this mode. For example, for Google Maps, the mobile's Google Maps should be in use, the route should be selected, the mobile screen should be turned horizontally (to be displayed in a larger image on the car stereo screen, otherwise it is displayed very small), and then the route is displayed via Mirror link.

The sound is very good and the Bluetooth works well for communication.
What prevents me from giving it 5 stars is that the Mirror link doesn't work, as I have tried it with several devices and there is no connection.
I might be doing something wrong, even though I followed the given instructions.
