This dock is driving me completely insane. I was so excited to learn that both the audio signal and the charging current both came through the same single cable, so I ordered the Motorola Vehicle Navigation Dock from Amazon for 59.99. When I received it, I noticed it had an issue where the audio would only come through my car speakers *sometimes*. When I dock the phone, the battery icon indicates that it is charging, but the CarDock app will not launch, nor will the sound play through my car speakers. Instead, the phone would just sit at the home screen and continue to play audio through the internal speaker. Once in a while, I will dock the phone and CarDock will launch and the audio will come through my speakers. So, I assumed I had a defective dock. I spent over 90 hellish minutes on the phone with Motorola support, and finally they agreed to send me a new dock. I received my warranty replacement dock today. To my extreme displeasure, it behaves in exactly the same way. Just to be clear with exactly what is wrong, if CarDock does not launch, the audio will not come through my speakers. And it will only launch maybe one out of every 3 docking attempts. I have tried manually launching CarDock using AnyCut, but I cannot get the shortcut to work. Although, I am not positive that launching the CarDock app will force the audio to connect, it could just be a bad connection of some sort. Which would have to be something wrong with the phone's micro USB port, since this is my second dock that acts like this. Can anyone help me here? Thanks in advance.
