We're planning on taking a long car trip at the end of the summer. I like the idea of the car dock for the Nexus One, but I saw a lot of dissatisfaction with people using it. There seemed to a lot of trouble with the phone not charging properly,and getting very hot in the dock. Does anyone know if any of those problems have gotten better after the Froyo 2.2 update? Is there any chance the dock will be improved, or are we just out of luck?
