First, let me say the phone (Unlocked 680 on T-Mobile) is paired and can make and recieve calls using Acura's HandsFreeLink (HFL). The problem is on many (but not all) outgoing calls the HFL drops out between dialing and the other person answering. If I say "Transfer" to reconnect with HFL, it will only work when the call is beginning (not while its still dialing). So most of my calls begin with one person saying hello and me saying "transfer" in response. Awkward....This never happens on incoming calls. Anyone using a 680 in an Acura that has rock steady bluetooth on outgoing calls care to offer advice?
