I have an LG-VN251S. I also have a 2013 Chevrolet Truck with Blue Tooth Phone capability. The phone and the truck pair fine and I can easily take incoming calls. I can make outgoing calls using the "Call" feature for the truck but only if I know the actual phone number or what I call a Voice Tag. It does not recognize my phone contact names at all. It does recognize however, about four old Voice Tags for specific contacts that I had put in one of my previous phones and they transferred over to my new one. How can I add new voice tags to existing contacts in this phone? I have even called LG but the individual did not understand what I was asking. When the phone is disconnected from the truck Blue Tooth the voice dialing feature works fine. These so called Voice Tags were like one or two word speed dials for specific contacts.
