I have a 2013 Optima and it automatically connected to my GNex when I flipped on (enabled) bluetooth on the phone. With the LG, it is not autoconnecting. I have to go into the car's phone menu and manually connect the LG. Note: I don't have to re "pair" it...it's there...just have to "connect" it. Removed the Gnex pairing before I started with the G2, so there shouldn't have been a problem there. Any ideas on what I'm missing? thx
