I'm having problems pairing my Charge to my car (Lexus). I previously had a Blackberry Storm and it paired fine so it isn't the car. When I try registering the phone with the car, I've confirmed that everything, such as the passkey, is entered the same in both but it says Connection Failed. Check your phone or passkey - which I did. Any ideas? Are there any special settings that I need to set on the phone?
