i paired my nextel blackberry 7100i with the siemens HKW-700 bluetooth car kit. when the two get paired and connect then the screen turn blank and says "connecting with the desktop" and i cant get onto the main screen to make phone calls or even do anything. once i turn off carkit it goes back to normal. this carkit also has the fuction to transfer the phonebook numbers and display them on the screen but that doesnt seem to work either. i tried starting a phonecall and then turning the carkit on and it paired and it worked but then once the phonecall ended it went back to that screen that doesnt allow me to do anything. does anyone know if there anything i can do or a setting that i am not doing corectly. i would appreciate any help with this. thank you so much.
