I've used my iPhone with a blue tooth device in my car. I have replaced the device and deleted the old one from the memory of my iPhone (I think!). I have also reset the iPhone, and now need it to work with a new device for my car. However my iPhone cannot find other blue tooth devices in its vicinity... e.g. computer, another iPhone... etc (although those devices can 'see' my iPhone!). All that happens is that in General Settings the 'searching...' section in bluetooth keeps going round in circles - ever looking, but never finding! Any help to resolve this will be gratefully received.
