I like the head unit ok, and it's got good sound. What I don't like: 1. It doesn't save that you had random on when playing from the USB or SD card. This is actually more annoying that it sounds. 2. Randomize isn't very random. The programmers obviously didn't learn how to properly perform a random function, which is harder than it sounds - I've dealt with the problem myself in firmware I've developed before. 3. Bluetooth often doesn't work right at all 4. FM sensitivity is only Ok. It gets static faster than other head units I've got.
