I have gained this part about three weeks ago and am completely satisfied. Actually only intended to connect my phone to the car radio, you can thus also with pretty good quality music in MP3 format on a USB stick or SD card on the car radio transmitted. However, the search of certain titles while driving is actually un- possible because the display is very small. To transmit conversations over the phone (mobile phone) to the car radio, I am very satisfied, the phone perfectly adequate sound, total hands-free operation via the mobile phone itself. His own voice you have a little increase (loud talking). Ultimately, I am completely satisfied for that price!
