Hello, I ordered this 2 times, and by different vendors. I wonder if users were able to operate it directly. Because in my case as the first, the second; after being connected to the iPhone or iPod, this one will start charging but I have never seen the frequencies appear on the LCD screen. So, I wonder if the problem is with the product that was never on, or my car stereo (standard Megane II). Someone there an idea or can describe me when the LCD screen is switched on? Should he leave the transmitter load before use?
