device works without major appearance problem a little chip, especially at the keys, I just tried his a priori because we just watch videos on the screen, considering the size of the screen I remain skeptical so in recognition with my car radio pioneer who dated but good quality and pregnant average, no problem, the frequencies are right away and was amused to change the indicated frequencies; nothing wrong, let the party that has annoyed the sound itself, I add that I am using for rendering sound from mp3 files, so the record is pretty bad, let me explain, if we base on the volume of MP4 thoroughly (disaster) it generates inaudible crackling so we must find a balance between the volume of MP4 and the car radio amplifier for my part it's still fair because all files are accompanied by many breath with time to time crunches and crackles, regarding the remote control, it's a gadget, you press volume and this is another function that activates and she does not like the cold I've tested the morning starting at work with a temperature of 9 ° and she answered nothing in conclusion: device is very sensitive to parasite, its a very convenient low volume, very low-end remote but everything for a small price
