Kenwood KDC-BT640U

Nice sound. There are a lot of things that can be configured, but not everything has been tried yet. I installed this to replace the standard radio in my Toyota Aygo. A world of difference (new speakers were also installed immediately). Bluetooth calling is super easy to set up and with the included microphone it is noise-free and crystal clear for the other end of the line. It's also nice that the radio can pair and remember multiple phones, so that if you regularly change cars with your partner without re-pairing etc., you can drive away immediately. The only downside as far as I'm concerned is that there is only 1 source button with which you have to go through all the inputs, so if you want to go from CD to radio, for example, you have to go through AUX, BT input, USB, Spotify, standby, etc. complete the whole round before you get to radio. A button for direct access to the radio and a button for all other input would have completed it for me, but otherwise I am very satisfied with this radio with all its options.
