Kowol, May 28, 2018 : Hello, I need help. I have replaced my Op3T with a OP6. In the last two days I tried to pairing OP6 with my Ford Mondeo. It worked for 2 minutes. Within this short period I could receive and make calls. Then both pairing partner shows that they connected. But when I tried to send a call, my car said that there is no network. But my phone shows full network connection. Have anybody an idea?
