This is a common problem. I think the first thing to do is to not take it personally. The team there clearly has a culture established and its going to take some time before getting everyone on board. I think the central problem is trust. That is not to say that you are not trustworthy, Im sure you are. However, the team is not familiar with you and you cant expect someone to give their trust to a new manager right from the start. I think the key would be to focus getting one person on board first by giving that one person a chance at situational leadership. That is to say, if you have a special project, allow someone else to take the lead. When you say, I trust you, that trust is generally reciprocated. Bottom line- its going to take time.
