Cons:Have to set the right frequency every time you turn on the car (if you don't use 87.0).No playback memorization.The LCD screen only displays the current frequency, the volume and the track number. It also shows a "P" when you press play.If player volume is over 25 the it distort the sound. Can be easily fixed by raising your radio volume (not the mp3 player volume).Sometimes there is noises coming into your frequency. This can be solved by touching by hand your mp3 player. This is a big cons because it can distract you from driving.Has a FM precision of 0.5 and not 0.55 (as normal radio) so you can't select frequencies like 90.35FM.Would be nice if it had an audio output to connect to other devices.Doesn't work with WAV files.I always walk out my car with the player remote in my hand.Very bad instructions. Badly translated and short
