I recently started to have problems with my bluetooth function. Calls have been dropped ie phone disconnects from my car's bluetooth all of a sudden. As well my car prompts me to download my phonebook and when I try to give permission to do it on my phone nothing is downloaded. I took my car into the dealership and they were able to pair and unpair several iphones successfully so it is probably a problem with my phone.Has anyone seen this problem and have a fix?
