My 535xi and my blackberry curve have stopped communicating properly. Up until 2 weeks ago they were perfectly synced. Then mysteriously, my contact list was missing information in my car's phone book. Many phone numbers no longer show the contact's name or photo. Other contacts that have more than 1 telephone number associated with it, cannot be opened. While I'm complainining about my Bluetooth connection, I might mention, the Bluetooth audio is no longer working either. I've taken out the battery and sim card from the phone, with no success. Thoughts?

Try to un-pair and pair again. Should work

You should take the help of Mechanician...

I have a curve 9360 as well and find that sometimes when I leave my car and lock (disconnecting bluetooth) it locks up my blackberry and pretty much slows it down to a crawl, as though it didn't unpair correctly.

Get an iphone..

its a work Blackberry and besides i can't stand touch screen keyboards, my wife has an Android and I can't type on it even though the screen is much bigger than the iphone...

You should try to check your phone settings?? after than may be your problem will be solved....
