I bought the radio about 3 months ago here. The installation itself was totally just as absolute layman for me. Everything you need to was included. I had to order for a few euros only an adapter specifically for my car (Ford), but I knew that already. So far I had no problems. The sound is really neat for the price, and also the radio function is impeccable. One point deduction, there is unfortunately, because the radio can not select a folder. I have about 300 songs on the USB flash drive in different folders. However, the radio can only the total number of songs and show the title number (eg song 15/300). If you want to hear a particular song you have rumsuchen rather long so often. For my case, I quickly got used to it and just noticed me the title number of my favorite songs. Conclusion: The device is perfect for those who want for little money a decent car radio, even the USB and SD card reads.
