I have an iPhone 3GS with me. I am having a connection problem of my iPhone with the car's hands-free system. My connection does not stay for a long period of time; every time it gets disconnected i need to connect it with the hands-free system. Initially when i connect the Bluetooth kit with the iphone it connect pretty well, but the connection drops after few minutes. What is the reason for this problem to occur with my device? If anyone has any solution for this problem, then please help me out.
