The antenna is useless. Even in the center of Athens, it gets interference and you can't hear anything.
The Bluetooth worked for about 5 days and then never again. It's the worst choice. It's not worth it even for its very low price, since you constantly hear with interference and very rarely clearly.

The worst purchase I've ever made!
Bluetooth is terrible. The device's microphone is terrible. I have to shout for the person I'm talking to to hear me! The USB doesn't work... I tried 5 different ones. And of course, the micro SD doesn't work either.
The menu has almost nothing. Especially the fader that is absolutely necessary.
And it goes without saying that it will be uninstalled and thrown away. I bought it for almost 20€. It's not worth even 1€!

In relation to its price, for now it does most of what it promises. The Bluetooth is satisfactory, although it lacks the quality found in systems with ten times the price. As for the negatives, the radio does not retain the stations you save in its memory.

For the money, it is very good and installation took 5 minutes. It plays USB, micro SD, and has Bluetooth connectivity so you can talk through the device without holding your phone.
