The installation was first no problem, old radio out new used, everything was great. Unfortunately, I then noticed that the radio was no preset stations and menu settings noted. I've then looked at the pin assignment of the radio and the car, with my KIA was the permanent plus on a position other than on the radio. But can the plug on the radio very easy to reposition. After that, everything went without problems. Otherwise, the sound is very good, better than my old one, it looks great and USB connection works best. Can I only recommend, brilliant for the price!
