I installed 2.2, and tried using my car dock, and it does not work. I removed the audio cable from the dock and plugged it directly to the phone and it works fine, but when I plug it back into the dock, and plug the phone back into the dock, it does not play. I tried a chat with Samsung Tech Support, and got as far as telling him what my problem was, only to have him tell me:
"Melvin: Unfortunately as we are in chat support not expertise on issues regarding phone car dock as we assist the technical issues, However I suggest you contact our Samsung Voice support where you can speak to our representative for the details."
I told him, "I thought I was chatting with Tech Support, and this is a technical issue, isn't it?"
Is there anyone out there having issue with their docks, or are they working?
