I'm sitting in my car right now waiting for some people to show up, and I decided to listen to my iPod through my car speakers. This works. This always works. But today it won't work. The car is telling me that media interface is not available. So I take my iPod out of the console and I look at it and it's plugged in properly. It even has the Mercedes logo showing on its little iPod screen. And below that it says OK to disconnect. So what is disconnecting my iPod from my car? I have disconnected and reconnected the cable on both ends. I have turned off the car completely and turned it back on. Nothing seems to work. Has anybody had this problem before? I remember once I was trying to listen to Sirius radio while on a road trip, and it became a little flaky. So I pulled over and, as this was back when I had concierge service, I called for help. They had me open my door turn off the engine turn on the engine push this button push that button. And that it all started working again. It's something like that going on now? Does anybody know the code? Thanks.
