I recently helped someone with their Infinity. Their contacts were once synced, but got a replacement phone and could not get phone to send contacts. It asked to copy the contacts when pairing, no contacts transferred. We tried the Infinity's separate Phonebook...Download Contacts portion of the system. It indicated downloading, again no transfer. Because I am a geek and can not fail, I searched her Galaxy S5 contacts menu and came upon a choice of sending contacts as one file(the default) or send individual contacts. I changed to Send Individual and deleted the phone, and repaired. Voila, the system said downloading which took a little longer than before and the contacts were stored in the cars Bluetooth. We have the same settings in our G3. Give it a try? Open Contacts....Setting....Transfer type
