Don't know what the other dude is doing wrong but mine works FLAWLESSLY...When I got my unit I wasn't exactly expecting a very high quality unit, but boy was I wrong..This thing is built like a brick.... very heavy and very sturdy parts... everything is solid, and shows excellent craftsmanship. The menu system is a bit ugly but everything is easy to find and easy to operate. Surprisingly, the blue-tooth detected my phone and worked right away, with no problems. The best way to play movies and music is right off the SD card... songs and vids load the quickest this way... Looking for a great , solid unit for under 300$... This is it... SD card support and it plays DIVX files.... WOW... PLUS, i didn't even have to do the toggle switch mod to get it to play while driving... mine worked out of the box..hahah..
