This started in the iphone forums, but i think it belongs here more so, so i'm just posting in HOPES of getting soem kind of answer or suggestions. I bought the iLuv fm transmitter/bluetooth transmitter. It is SUPPOSED to use the internal microphone to listen to you, and puts the person on the other end's voice through the speakers. I have sucessfully paired this item ONCE. I was holding it in my hand and un-paired and re-paired and then when i made the call, the option to choose that bluetooth item FINALLY came up. So i chose it and everything seemed to work. but it wasnt int he dock.. so i didnt change ANYTHING but i put it in the dock, and the choice for the bluetooth came up again, but this time it didnt put it through the speakers.. Ever since then, the choice for the bluetooth never came up when making a call, but in settings it said it was paired.. THEN i tried to unpair it again and re-pair and NOW its telling me that i entered an invalid pin.. THE PIN IS 0000!! cant mess that one up! Any suggestions. Has ANYONE used this with any sucess???
