Just installed Bluetooth Phonebook on my HTC One M8 because the contact list would not sync properly with the Kenwood DDX773BH. Contacts would come across but the phone numbers would be from other contact records. Bluetooth phonebook fixed that and contacts are shown with correct phone numbers on the Kenwood. However, this is only when I select "All Groups". If I select a few groups, such as Friends, Family, etc. the contacts again have phone numbers from other records in the phone book.
Is there something I'm missing? Another setting?
Thanks
