I Have had my F500Bt for 4 days and never had a single problem with it. It is running superbly. I do Not have it installed in my car. I plug it into the car charger in my Ford Focus 2008. The ipod comes up every time, The 16gb sd card works superbly. I have my portable dvd speakers plugged into the ipod classic 80gb and into the speaker input when using the sd card . My lg chocolate flip works superbly. Apart from the voice command given the wrong info sometimes it is working beautifully, For 199.96 dollars it was a steal. Highly recommend
