whacko

I apologize if I missed this somewhere else. My x920BT Voice Recognition has worked flawlessly for a few years until a few days ago. VR / Ipod Commands - Works Fine VR/ Calling actual phone numbers - Works Fine VR/ Contact name - Doesn't recognize contact names. All of the contact names are listed in the unit and I can dial by manually selecting their name in the menu. Has anyone else encountered this problem? Would a reset fix the problem? Thanks
