One of the few radio stations that can be operated logically. Almost like an original unit of a vehicle manufacturer. Press once on the large button: One. Overhead Press again: Mute. Long press: Off. If that was adjacent to the almost to idiocy operating logic of many Japanese units compared ... Most disturbs the brief display, with its only max. 8 characters, indicating default no MP3 tags, just the track number. Since a title or artist is hardly reliably detect. If you change the display by pressing the DISPLAY button, everything is by turning off the ignition again as before ... Typical japan-like garbage are also the tiny station buttons without clearance. When ID3 tags title, artist and album are accepted. But there is no way the songs to sort accordingly. And the logic according to which the device sorts the songs when playing itself is not visible. Also M3U playlists are not recognized. Quite frustrating. But folders and tracks have two each have their own keys with which you can display these in a targeted and then search. Reception and sound are at an intermediate level. No worse than many other low-cost equipment from China. Really good I find the separate Loudness button at the bottom left, with which you can give songs like Drive by REM short rums. Although the device comes from China, but is Designed by Philips. This can be seen clearly on the operating concept that is logically and clearly oriented to European habits. Philips should the JVC KD-X50 look at times. It has everything that the C152 lacks even a flatter panel that does not protrude as far from the cockpit. But has no preset buttons and is also not so easy to use. The Bluetooth hands-free I have not tried. Who is too stupid to simultaneously use a phone while driving, should be remain the driving.
